This application is a § 371 National State Application of PCT/EP2015/064802, filed Jun. 30, 2015, which claims priority to European Application No. 14175710.4 filed Jul. 4, 2015.
Primarily, the present invention relates to compounds of the formula (I) defined below and to their use as herbicides, in particular for controlling broad-leaved weeds and/or weed grasses in crops of useful plants and/or as plant growth regulators for influencing the growth of crops of useful plants. The present invention also relates to herbicidal or plant growth-regulating compositions comprising one or more compounds of the formula (I). Moreover, the present invention relates to processes for preparing the compounds of the formula (I).
In their application, crop protection agents known to date for the selective control of harmful plants in crops of useful plants or active ingredients for controlling unwanted vegetation sometimes have disadvantages, be it (a) that they have no or else insufficient herbicidal activity against particular harmful plants, (b) that the spectrum of harmful plants which can be controlled with an active ingredient is not wide enough, (c) that their selectivity in crops of useful plants is too low and/or (d) that they have a toxicologically unfavorable profile. Furthermore, some active ingredients which can be used as plant growth regulators for a number of useful plants cause unwanted reduced harvest yields in other useful plants or are not compatible with the crop plant, or only within a narrow application rate range. Some of the known active ingredients cannot be produced economically on an industrial scale owing to precursors and reagents which are difficult to obtain, or they have only insufficient chemical stabilities. In the case of other active ingredients, the activity is too highly dependent on environmental conditions, such as weather and soil conditions.

EP-A-0 005 341 describes herbicidal esters and amides of 4-cyano-3,4-diphenylbutanoic acids which are optionally substituted at the phenyl radicals. According to EP-A-0 005 341, the threo isomers are generally suitable for the non-selective control of harmful plants, whereas the erythro/threo isomer mixtures are suitable for the selective control of harmful plants in some crops of useful plants. Moreover, EP-A-0 005 341 mentions that the 2 enantiomers belonging to the threo form have different activities, which was investigated in an exemplary manner on the different activities of the enantiomers of the enantiomer pair of 4-cyano-3,4-diphenylbutanoic acid unsubstituted in the phenyl radicals.
EP-A-0 266 725 discloses some erythro/threo isomer mixtures which can be used selectively for controlling weeds in rice crops.

WO 2014/095879 A1 describes substituted 4-cyano-3-(pyridyl)-4-phenylbutanoates and their use as herbicides and plant growth regulators.
The herbicidal activity of these known compounds, in particular at low application rates, and/or their compatibility with crop plants remain deserving of improvement.
For the reasons stated, there is still a need for potent herbicides and/or plant growth regulators for the selective use in crop plants or the use on non-crop land, where these active ingredients preferably should have further advantageous properties in application, for example with respect to their compatibility with crop plants.
It is the primary object of the present invention to provide compounds having herbicidal activity (herbicides) which are highly effective against economically important harmful plants even at relatively low application rates and can be used selectively in crop plants, preferably with good activity for harmful plants, and at the same time preferably have good compatibility with crop plants. Preferably, these herbicidal compounds should be particularly effective and efficient against a broad spectrum of weed grasses and preferably also have good activity against a large number of weeds.
Surprisingly, it has now been found that this object is achieved by the compounds of the formula (I) defined below and their salts.
The present invention therefore relates to the compounds of the formula (I) and/or their salts,
in which
The compounds of the formula (I) according to the invention and/or their salts have excellent herbicidal activity against a broad spectrum of economically important mono- and dicotyledonous annual harmful plants. The compounds according to the invention also have good control over perennial harmful plants which are difficult to control and produce shoots from rhizomes, root stocks or other perennial organs.
The compounds of the formula (I) according to the invention and/or their salts, for example compared to the compounds described in WO 2012/126765 A1, generally have more potent action at the same dosage, for example against weed grasses. Furthermore, the compounds according to the invention have a broader spectrum of activity against weeds, i.e. the compounds according to the invention and/or their salts can be used to control effectively a relatively large number of different weeds.
The compounds of the formula (I) according to the invention and/or their salts have proven to be very effective in controlling harmful plants such as Alopecurus myosuroides, Avena fatua, Cyperus esculentus, Echinochloa crus-galli, Lolium multiflorum, Setaria viridis, Abutilon theophrasti, Amaranthus retroflexus, Polygonum convolvulus (=Fallopia convolvulus), Stellaria media, Viola tricolor, and Veronica persica, where the preferred and particularly preferred compounds according to the invention exhibited in the biological tests an 80% to 100% herbicidal action against one, several or all of the specified harmful plants, and in so doing simultaneously more acceptable and mostly very slight damage to the useful plant.
In addition, the compounds of the formula (I) according to the invention and/or their salts show particularly good activity in the pre-emergence method, in particular against weed grasses. The pre-emergence activity of the compounds according to the invention is generally better than the pre-emergence activity of the compounds described in WO 2012/126765 A1.
Furthermore, it has been found that the compounds of the formula (I) according to the invention and/or their salts show this better pre-emergence action particularly selectively in certain crops, in particular in oilseed rape, soya beans, cotton and cereals (and here in particular in maize, barley, wheat, rye, oats, triticale, millet varieties, rice).
In general, the compounds of the formula (I) according to the invention also have a considerably broader activity spectrum.
In the formula (I), the formula “(R2)n” means n radicals R2 which are attached as substituents at the heteroaromatic radical Q, where the radicals R2 in the case of n greater than 1 may be identical or different and have the meaning mentioned in each case in more detail. In the case n=0, the heteroaromatic radical Q is not substituted by substituents R2.
In the formula (I), the formula “(R3)m” means m radicals R3 which are attached as substituents at the phenyl ring in question, where the radicals R3 in the case of n greater than 1 may be identical or different and have the meaning mentioned in each case in more detail. In the case n=0, the phenyl ring in question is not substituted by substituents R3, i.e. all ring carbon atoms of the phenyl ring in positions 2 to 6 are attached to a hydrogen atom.
In the case of R1═H or in the case of suitable acidic substituents, the compounds of the formula (I) are able to form salts by reaction with bases where the acidic hydrogen is replaced by an agriculturally suitable cation.
By addition of a suitable inorganic or organic acid onto a basic group, such as, for example, amino or alkylamino, the compounds of the formula (I) are able to form salts. Suitable acidic groups present, such as, for example, carboxylic acid groups, are able to form inner salts with groups which for their part can be protonated, such as amino groups.
The compounds of the formula (I) may preferably be present in the form of agriculturally usable salts, where the type of salt is otherwise generally immaterial. In general, suitable salts are the salts of those cations or the acid addition salts of those acids whose cations and anions, respectively, have no adverse effect on the herbicidal activity of the compounds of the formula (I).
Suitable cations are in particular ions of the alkali metals, here preferably lithium, sodium or potassium, of the alkaline earth metals, here preferably calcium or magnesium, and of the transition metals, here preferably manganese, copper, zinc or iron. The cation used may also be ammonium (NH4+) or substituted ammonium, where one to four hydrogen atoms may be replaced here by (C1-C4)alkyl, hydroxy-(C1-C4)alkyl, (C1-C4)alkoxy-(C1-C4)alkyl, hydroxy(C1-C4)alkoxy-(C1-C4)alkyl, phenyl or benzyl, preferred ammonium ions are ammonium, dimethylammonium, diisopropylammonium, tetramethylammonium, tetrabutylammonium, 2-(2-hydroxyeth-1-oxy)eth-1-ylammonium, di(2-hydroxyeth-1-yl)ammonium, trimethylbenzylammonium. Also suitable are phosphonium ions, sulfonium ions, preferably tri-(C1-C4)alkylsulfonium, in particular trimethylsulfonium, or sulfoxonium ions, preferably tri(C1-C4)alkylsulfoxonium, in particular trimethylsulfoxonium.

In formula (I) and in all subsequent formulae, chemical radicals are referred to by names which are collective terms for the enumeration of individual group members or specifically refer to individual chemical radicals. Here, terms are used which are familiar to the person skilled in the art or have the meanings defined below.
A hydrolyzable radical (see definition of R1) is a radical which can be hydrolyzed under the application conditions, for example a radical which can be hydrolyzed even in the spray liquor or in particular under the physiological conditions in plants, where a compound of the formula (I) where R1 is not hydrogen is hydrolyzed to the corresponding compound of the formula (I) where R1═H (hydrogen). Expressly, the definition of the hydrolyzable radicals also includes the radicals where R1=hydrocarbon radical or heterocyclyl radical, the two last-mentioned radicals being unsubstituted or substituted, even if some of them are hydrolyzable comparatively slowly.
A hydrocarbon radical is an aliphatic, cycloaliphatic or aromatic monocyclic or, in the case of an optionally substituted hydrocarbon radical, also a bicyclic or polycyclic organic radical based on the elements carbon and hydrogen, including, for example, the radicals alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, phenyl, naphthyl, indanyl, indenyl, etc. This applies correspondingly to hydrocarbon radicals in composite meanings, such as hydrocarbonoxy radicals or other hydrocarbon radicals attached via heteroatom groups.
Unless defined in more detail, the hydrocarbon radicals preferably have 1 to 20 carbon atoms, more preferably 1 to 16 carbon atoms, in particular 1 to 12 carbon atoms.
The hydrocarbon radicals, also in the special radicals alkyl, alkoxy, haloalkyl, haloalkoxy, alkylamino and alkylthio, and also the corresponding unsaturated and/or substituted radicals may in each case be straight-chain or branched in the carbon skeleton.
The expression “(C1-C4)alkyl” is shorthand for alkyl having from 1 to 4 carbon atoms, i.e. encompasses the radicals methyl, ethyl, 1-propyl, 2-propyl, 1-butyl, 2-butyl, 2-methylpropyl or tert-butyl. General alkyl radicals having a larger specified range of carbon atoms, for example “(C1-C6)alkyl”, correspondingly also encompass straight-chain or branched alkyl radicals having a greater number of carbon atoms, i.e. in this example also the alkyl radicals having 5 and 6 carbon atoms.
Unless stated specifically or differently, preference is given to the lower carbon skeletons, for example having from 1 to 6 carbon atoms, or having from 2 to 6 carbon atoms in the case of unsaturated groups, in the case of the hydrocarbon radicals such as alkyl, alkenyl and alkynyl radicals, including in composite radicals. Alkyl radicals, including in the combined definitions such as alkoxy, haloalkyl, etc., are, for example, methyl, ethyl, n- or i-propyl, n-, t- or 2-butyl, pentyls, hexyls such as n-hexyl, hexyl and 1,3-dimethylbutyl, heptyls such as n-heptyl, 1-methylhexyl and 1,4-dimethylpentyl; alkenyl and alkynyl radicals are defined as the possible unsaturated radicals corresponding to the alkyl radicals; alkenyl is, for example, vinyl, allyl, 1-methyl-2-propenyl, 2-methyl-2-propenyl, 2-butenyl, pentenyl, 2-methylpentenyl or hexenyl group, preferably allyl, 1-methylprop-2-en-1-yl, 2-methylprop-2-en-1-yl, but-2-en-1-yl, but-3-en-1-yl, 1-methylbut-3-en-1-yl or 1-methylbut-2-en-1-yl.
Alkenyl also includes in particular straight-chain or branched hydrocarbon radicals having more than one double bond, such as 1,3-butadienyl and 1,4-pentadienyl, but also allenyl or cumulenyl radicals having one or more cumulated double bonds, for example allenyl (1,2-propadienyl), 1,2-butadienyl and 1,2,3-pentatrienyl.
Alkynyl is, for example, propargyl, but-2-yn-1-yl, but-3-yn-1-yl, 1-methylbut-3-yn-1-yl. Alkynyl also includes, in particular, straight-chain or branched hydrocarbon radicals having more than one triple bond or else having one or more triple bonds and one or more double bonds, for example 1,3-butatrienyl or 3-penten-1-yn-1-yl.
A 3- to 9-membered carbocyclic ring is (C3-C9)cycloalkyl or (C5-C9)cycloalkenyl.
(C3-C9)Cycloalkyl is a carbocyclic saturated ring system having preferably 3-9 carbon atoms, for example cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl or cyclononyl. In the case of substituted cycloalkyl, cyclic systems with substituents are included, where the substituents may also be bonded by a double bond on the cycloalkyl radical, for example an alkylidene group such as methylidene.
(C5-C9)Cycloalkenyl is a carbocyclic, nonaromatic, partially unsaturated ring system having 5-9 carbon atoms, for example 1-cyclobutenyl, 2-cyclobutenyl, 1-cyclopentenyl, 2-cyclopentenyl, 3-cyclopentenyl, or 1-cyclohexenyl, 2-cyclohexenyl, 3-cyclohexenyl, 1,3-cyclohexadienyl or 1,4-cyclohexadienyl. In the case of substituted cycloalkenyl, the explanations for substituted cycloalkyl apply correspondingly.
Alkylidene, for example also in the form of (C1-C10)alkylidene, is the radical of a straight-chain or branched alkane which is bonded via a double bond, the position of the bonding site not being fixed. In the case of a branched alkane, the only positions possible are, of course, those in which two hydrogen atoms can be replaced by the double bond; radicals are, for example, ═CH2, ═CH—CH3, ═C(CH3)—CH3, C(CH3)—C2H5 or C(C2H5)—C2H5.
“Halogen” preferably refers to the group consisting of fluorine, chlorine, bromine and iodine. Haloalkyl, -alkenyl and -alkynyl are alkyl, alkenyl and alkynyl, respectively, which are partially or fully substituted by identical or different halogen atoms, preferably from the group consisting of fluorine, chlorine and bromine, in particular from the group consisting of fluorine and chlorine, for example monohaloalkyl, perhaloalkyl, CF3, CHF2, CH2F, CF3CF2, CH2FCHCl, CCl3, CHCl2, CH2CH2C1; haloalkoxy is, for example, OCF3, OCHF2, OCH2F, CF3CF2O, OCH2CF3 and OCH2CH2C1; this applies correspondingly to haloalkenyl and other halogen-substituted radicals.
Aryl is a mono-, bi- or polycyclic aromatic system, for example phenyl, naphthyl, tetrahydronaphthyl, indenyl, indanyl, pentalenyl, fluorenyl and the like, preferably phenyl.
Optionally substituted aryl also includes polycyclic systems, such as tetrahydronaphthyl, indenyl, indanyl, fluorenyl, biphenylyl, where the point of attachment is at the aromatic system.
A heterocyclic radical (heterocyclyl) comprises at least one heterocyclic ring (=carbocyclic ring in which at least one carbon atom is replaced by a heteroatom, preferably by a heteroatom from the group consisting of N, O, S, P, B, Si, Se), which is saturated, unsaturated or heteroaromatic and may be unsubstituted or substituted, where the point of attachment is located at a ring atom. Unless defined otherwise it preferably contains one or more, in particular 1, 2 or 3, heteroatoms in the heterocyclic ring, preferably from the group consisting of N, O, and S; it is preferably an aliphatic heterocyclyl radical having 3 to 7 ring atoms or a heteroaromatic radical having 5 or 6 ring atoms. The heterocyclic radical may, for example, be a heteroaromatic radical or ring (heteroaryl), such as, for example, a monocyclic, bicyclic or polycyclic aromatic system in which at least 1 ring contains one or more heteroatoms.
If the heterocyclyl radical or the heterocyclic ring is optionally substituted, it may be fused to other carbocyclic or heterocyclic rings. Preference is given to benzo-fused heterocyclic or heteroaromatic rings.
Optionally substituted heterocyclyl also includes polycyclic systems, such as, for example, 8-aza-bicyclo[3.2.1]octanyl or 1-aza-bicyclo[2.2.1]heptyl. Optionally substituted heterocyclyl also includes spirocyclic systems, such as, for example, 1-oxa-5-aza-spiro[2.3]hexyl.

When a base structure is substituted “by one or more radicals” from a list of radicals (=group) or a generically defined group of radicals, this in each case includes simultaneous substitution by a plurality of identical and/or structurally different radicals.
Substituted radicals, such as a substituted alkyl, alkenyl, alkynyl, cycloalkyl, aryl, phenyl, benzyl, heterocyclyl and heteroaryl radical, are, for example, a substituted radical derived from the unsubstituted base structure, where the substituents are, for example, one or more, preferably 1, 2 or 3, radicals from the group of halogen, alkoxy, alkylthio, hydroxyl, amino, nitro, carboxyl, cyano, azido, alkoxycarbonyl, alkylcarbonyl, formyl, carbamoyl, mono- and dialkylaminocarbonyl, substituted amino such as acylamino, mono- and dialkylamino, and alkylsulfinyl, alkylsulfonyl and, in the case of cyclic radicals, also alkyl, haloalkyl, alkylthioalkyl, alkoxyalkyl, optionally substituted mono- and dialkylaminoalkyl and hydroxyalkyl; in the term “substituted radicals”, such as substituted alkyl, etc., substituents include, in addition to the saturated hydrocarbon-containing radicals mentioned, corresponding unsaturated aliphatic and aromatic radicals, such as optionally substituted alkenyl, alkynyl, alkenyloxy, alkynyloxy, phenyl and phenoxy, etc. In the case of substituted cyclic radicals having aliphatic moieties in the ring, cyclic systems with those substituents which are bonded on the ring by a double bond are also included, for example substituted by an alkylidene group such as methylidene or ethylidene.
The term “radicals from the group consisting of” followed by a group (list of the substituents) is, wherever used, synonymous with “radicals selected from the group consisting of” (list of the substituents).
The substituents mentioned by way of example (“first substituent level”) may, if they contain hydrocarbonaceous moieties, optionally be further substituted therein (“second substituent level”), for example by one of the substituents as defined for the first substituent level. Corresponding further substituent levels are possible. The term “substituted radical” preferably embraces just one or two substituent levels.

Here, with preference benzo-fused systems based on the base structure are formed.
Optionally substituted phenyl is preferably unsubstituted phenyl or phenyl which is substituted by one or more radicals from the group consisting of halogen, cyano, (C1-C4)-alkyl, (C1-C4)-haloalkyl, (C1-C4)-alkoxy-(C1-C4)alkyl, (C1-C4)-alkoxy, (C1-C4)-haloalkoxy, (C1-C4)-alkoxy-(C1-C4)-alkoxy, alkylthio and nitro, in particular phenyl which is optionally substituted by one or more radicals from the group consisting of halogen, (C1-C4)-alkyl, (C1-C4)-haloalkyl and (C1-C4)-alkoxy.
In the case of substituents having carbon atoms, preference is given to those having 1 to 6 carbon atoms, preferably to those having 1 to 4 carbon atoms, especially to those having 1 or 2 carbon atoms.

The same applies to substituted hydroxylamino or hydrazino.
Acyl is a radical of an organic acid which arises in a formal sense by removal of a hydroxyl group on the acid function, and the organic radical in the acid may also be bonded to the acid function via a heteroatom. Examples of acyl are the radicals of a carboxylic acid and radicals of acids derived therefrom, such as those of thiocarboxylic acid, optionally N-substituted iminocarboxylic acids or the radical of carbonic monoesters, N-substituted carbamic acid, sulfonic acids, sulfinic acids, N-substituted sulfonamide acids, phosphonic acids or phosphinic acids.
Acyl is, for example, formyl, alkylcarbonyl, here preferably [(C1-C4)-alkyl]carbonyl, phenylcarbonyl, alkyloxycarbonyl, phenyloxycarbonyl, benzyloxycarbonyl, alkylsulfonyl, alkylsulfinyl, N-alkyl-1-iminoalkyl and other radicals of organic acids. The radicals may each for their part be substituted in the alkyl or phenyl moiety, for example in the alkyl moiety by one or more radicals from the group of halogen, alkoxy, phenyl and phenoxy; examples of substituents in the phenyl moiety are the substituents already mentioned above in general for substituted phenyl.
Acyl is preferably an acyl radical in the narrower sense, i.e. a radical of an organic acid in which the acid group is bonded directly to the carbon atom of an organic radical, for example formyl, alkylcarbonyl such as acetyl or [(C1-C4alkyl]carbonyl, phenylcarbonyl, alkylsulfonyl, alkylsulfinyl and other radicals of organic acids.
In a preferred embodiment, acyl is an alkanoyl radical having 1 to 8 carbon atoms, preferably 1 to 6 carbon atoms, particularly preferably 1 to 4 carbon atoms. Here, (C1-C4)alkanoyl is the radical of an alkanoic acid having 1 to 6 carbon atoms formed after removal of the OH group of the acid group, i.e. formyl, acetyl, n-propionyl, isopropionyl, n-, iso-, sec- or tert-butanoyl, n-, iso-, sec- or tert-pentanoyl, n-, iso- or sec-hexanoyl.
The “yl position” of a radical denotes the carbon atom having the free bond.

The invention also provides all stereoisomers which are encompassed by formula (I) and mixtures thereof. Compounds of the formula (I) contain two or more asymmetric carbon atoms, and may also contain double bonds, the stereochemistry of which is not stated separately in the general formula (I).

The compounds of the formula (I) according to the invention can have (2,3)-erythro configuration, i.e. correspond to the compounds of the following formulae (I eryrthro-1) and (I eryrthro-2):
Furthermore, it has been found that the compounds of the formula (I) according to the invention and/or their salts or (Ia) and/or their salts which are (2,3)-threo-configured have better herbicidal properties than the corresponding (2,3)-erythro-configured compounds. Accordingly, (2,3)-threo-configured compounds of the formulae (I) and (Ia) and their salts are preferred. The same applies accordingly to compositions according to the invention.
Accordingly, preference according to the invention is given to mixtures and compositions in which the molar ratio of a (2,3)-threo-configured compound of the formula (I) to the corresponding (2,3)-erythro-configured compound of the formula (I) is greater than 1, more preferably greater than 2, particularly preferably greater than 3 and especially preferably greater than 4.

in which
R1, R2, R3, n and m each have the meaning mentioned above, preferably one of the meanings given in each case as being preferred or particularly preferred.

By virtue of their even better property profile, in particular their even better herbicidal activity, special preference is given to the (2R,3R)-configured pentanonitrile derivatives of the formulae (I) and (Ia), preferably in the stereochemical purities stated above. As a consequence, compounds of the formulae (I threo-1) and (Ia threo-1) are particularly preferred in the context of the present invention. The absolute configuration of these (2R,3R)-configured pentanonitrile derivatives was assigned by X-ray structural analysis.
That stated above applies accordingly to mixtures according to the invention and compositions according to the invention.
The compounds of the formula (I) according to the invention can be prepared by various processes.
In the processes described below, in some cases solvents are employed. In this context, “inert solvents” refers in each case to solvents which are inert under the particular reaction conditions, but which do not have to be inert under any reaction conditions. In the processes below, the reactions described can alternatively also be carried out in a microwave reactor.
The compounds according to the invention can be prepared by methods known per se. Here, the starting material may, for example, be compounds of the formula (E). Compounds of the formula (E) are known from the prior art, for example from WO 2013/092500 A1. The scheme below shows, in an exemplary manner, how the compounds according to the invention can be prepared.
Here, R1, R2, R3, n and m each have the (preferred or particularly preferred) meaning mentioned above, and R represents hydrogen or an organic radical, preferably a radical selected from the group of the radicals defined above for R1.
With respect to “Step 1” of the above scheme:
Methods for the selective reduction of compounds of the formula (E) to give corresponding compounds of the formula (Ia) are known to the person skilled in the art from the prior art and described, for example, in European Journal of Organic Chemistry 2009, (11), 1806-1811 or in WO 2012/076513 A1. Preferably, the selective reduction in this case is carried out using borohydrides, with preference using borohydrides of alkali metal borohydrides, in particular of lithium borohydride, sodium borohydride or potassium borohydride, and in turn preferably in the presence of a lithium halide, preferably in the presence of lithium chloride. Here, this reduction can be carried out in a protic organic solvent such as, for example, ethanol (see, for example, WO 2011/014383), or an aprotic organic solvent such as, for example, tetrahydrofuran (THF), here preferably by heating under reflux.
With respect to “Step 2” of the above scheme:
The present optional further reaction (nucleophilic substitution) of the primary alcohol (Ia) obtained in “Step 1” with R1—X1 (where X1 represents a leaving group) to give compounds of the formula (I) is known in principle to the person skilled in the art and described, for example, in Journal of Organic Chemistry 2011, 76(3), 811-819. Here, the nucleophilic substitution is preferably carried out in the presence of 4-(dimethylamino)pyridine. The reaction can also be carried out, for example, in an aprotic organic solvent such as tetrahydrofuran (THF) or dichloromethane, if appropriate at elevated temperature, for example by heating under reflux.
Accordingly, the present invention also relates to a process for preparing a compound of the formula (I) according to the invention and/or a salt thereof, characterized in that a compound of the formula (E)
is converted by reduction into a compound of the formula (Ia)
and the compound (Ia) is optionally reacted further to give a compound of the formula (I), provided R1 does not represent hydrogen,
where
R represents hydrogen or an organic radical, preferably a radical selected from the group of the radicals defined above for R1, with preference selected from one of the radicals characterized as being preferred,
and
R2, R3, m and n each have the meaning defined above, and are preferably in each case selected from one of the groups of radicals characterized as being preferred.
The starting materials (E) used for preparing the compounds of the formula (Ia) or (I) are known from the literature cited or can be prepared analogously to the literature cited.
To prepare the compounds (Ia) or (I) according to the invention, it is also possible to use the corresponding diastereomer mixtures in the form of their racemic mixtures.
If stereochemically enriched compounds of the formula (E) mentioned above are used in the process according to the invention, it is possible to obtain the corresponding stereochemically enriched compounds of the formula (Ia) or (I).
Solvents suitable for this purpose are, for example, organic solvents such as:
In individual cases, it is also appropriate to use inorganic solvents such as water or mixtures of organic solvents with water.
Suitable conditions and catalysts for the preparation of compounds of the formula (I) in which R1 does not represent H from compounds of the formula (Ia), for example by esterification, are known to the person skilled in the art.
The conversion of compounds of the formula (Ia) into compounds of the formula (I) in which R1 does not represent H can be carried out in the presence of a base, for example a base from the group of the inorganic bases such as the alkali metal and alkaline earth metal hydroxides, for example lithium hydroxide, sodium hydroxide, potassium hydroxide or calcium hydroxide, the alkali metal and alkaline earth metal oxides, for example lithium oxide, sodium oxide, calcium oxide or magnesium oxide, the alkali metal and alkaline earth metal hydrides, for example lithium hydride, sodium hydride, potassium hydride or calcium hydride, the alkali metal amides, for example lithium amide, sodium amide or potassium amide, the alkali metal and alkaline earth metal carbonates, for example lithium carbonate, potassium carbonate or calcium carbonate, the alkali metal bicarbonates, for example sodium bicarbonate, or the organometallic compounds such as, preferably, the alkali metal alkyls, for example methyllithium, butyllithium or phenyllithium, the alkylmagnesium halides, for example methylmagnesium chloride, or the alkali metal and alkaline earth metal alkoxides, for example sodium methoxide, sodium ethoxide, potassium ethoxide, potassium tert-butoxide or dimethoxymagnesium.
The bases used can also be organic bases, for example from the group of the tertiary aliphatic amines, for example trimethylamine, triethylamine, tributylamine, diisopropylethylamine or N-methylpiperidine, or the aromatic tertiary amines, for example pyridine or substituted pyridines such as collidine, lutidine or 4-dimethylaminopyridine, or the bicyclic amines such as 7-methyl-1,5,7-triazabicyclo[4.4.0]-dec-5-ene or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU).
Preferred bases are, for example, lithium hydroxide, potassium carbonate, potassium tert-butoxide, lithium bis(trimethylsilyl)amide, pyridines, substituted pyridines, 7-methyl-1,5, 7-triazabicyclo[4.4.0]-dec-5-ene or DBU.
The amount of base may generally vary within wide limits. For example, it may be expedient to employ the base in catalytic amounts, in substoichiometric amounts, in equimolar amounts or in excess. A preferably liquid organic base may optionally also be used as solvent.
Suitable catalysts for the conversion of compounds of the formula (Ia) into compounds of the formula (I) in which R1 is not H may also be acidic catalysts, for example from the group of the inorganic acids, for example Broensted acids, such as hydrofluoric acid, hydrochloric acid, hydrobromic acid, sulfuric acid or perchloric acid, or Lewis acids, such as boron trifluoride, aluminum trichloride, iron(III) chloride, tin(IV) chloride, titanium(IV) chloride, scandium(III) triflate or zinc(II) chloride, and also organic acids, for example formic acid, acetic acid, propionic acid, oxalic acid, toluenesulfonic acid, benzenesulfonic acid, camphorsulfonic acid, citric acid or trifluoroacetic acid.
The reaction mixtures obtained are worked up in a customary manner, for example by mixing with water, separating the phases and optionally chromatographic purification of the crude products. Some of the compounds are obtained in the form of colorless or slightly brownish viscous oils which are purified or freed from volatile components under reduced pressure and at moderately elevated temperature.
If the compounds are obtained as solids, the purification can also be carried out by recrystallization or digestion. If individual compounds (I) cannot be obtained in a satisfactory manner by the routes described above, they can be prepared by derivatization of other compounds (I) or (Ia).
Suitable isolation methods, purification methods and methods for separating stereoisomers of compounds of the formula (I) or (Ia) are methods generally known to the person skilled in the art from analogous cases, for example by physical processes such as crystallization, chromatographic methods, in particular column chromatography and HPLC (high pressure liquid chromatography), distillation, optionally under reduced pressure, extraction and other methods, any mixtures that remain can generally be separated by chromatographic separation, for example on chiral solid phases. Suitable for preparative amounts or on an industrial scale are processes such as crystallization, for example of diastereomeric salts which can be obtained from the diastereomer mixtures using optically active acids and, if appropriate, provided that acidic groups are present, using optically active bases.
Optically active acids which are suitable for optical resolution by crystallization of diastereomeric salts are, for example, camphorsulfonic acid, camphoric acid, bromocamphorsulfonic acid, quinic acid, tartaric acid, dibenzoyltartaric acid and other analogous acids; suitable optically active bases are, for example, quinine, cinchonine, quinidine, brucine, 1-(S)- or 1-(R)-phenylethylamine and other analogous bases.
The crystallizations are then in most cases carried out in aqueous, alcoholic or aqueous-organic solvents, where the diastereomer which is less soluble precipitates first, if appropriate after seeding. One enantiomer of the compound of the formula (I) is then liberated from the precipitated salt, or the other is liberated from the crystallizate, by acidification or using a base.
As an alternative to the optical resolution methods mentioned, enantioselective processes starting with stereochemically pure starting materials are in principle also suitable for preparing the (threo) enantiomers.
The following acids are generally suitable for preparing the acid addition salts of the compounds of the formula (I): hydrohalic acids, such as hydrochloric acid or hydrobromic acid, furthermore phosphoric acid, nitric acid, sulfuric acid, mono- or bifunctional carboxylic acids and hydroxycarboxylic acids, such as acetic acid, maleic acid, succinic acid, fumaric acid, tartaric acid, citric acid, salicylic acid, sorbic acid, or lactic acid, and also sulfonic acids, such as p-toluenesulfonic acid and 1,5-naphthalenedisulfonic acid. The acid addition compounds of the formula (I) can be obtained in a manner known per se by the customary methods for forming salts, for example by dissolving a compound of the formula (I) in a suitable organic solvent, such as, for example, methanol, acetone, methylene chloride or benzene, and adding the acid at temperatures of from 0 to 100° C., and they can be isolated in a known manner, for example by filtration, and, if appropriate, purified by washing with an inert organic solvent.
Base addition salts of the compounds of the formula (I) can be prepared, for example, in polar solvents such as, for example, water, methanol or acetone, at temperatures of from 0 to 100° C. Examples of bases which are suitable for the preparation of such salts are, for example, alkali metal carbonates, such as potassium carbonate, alkali metal hydroxides and alkaline earth metal hydroxides, for example NaOH or KOH, alkali metal hydrides and alkaline earth metal hydrides, for example NaH, alkali metal alkoxides and alkaline earth metal alkoxides, for example sodium methoxide or potassium tert-butoxide, or ammonia, ethanolamine or quaternary ammonium hydroxide.
A collection of compounds of the formula (I) can additionally be prepared in a parallel or combinatorial manner, it being possible for this to take place in a manual, partly automated or completely automated manner. In this connection, it is possible to automate the reaction procedure, the work-up or the purification of the products and/or intermediates.
For the parallelized reaction procedure and work-up it is possible to use a range of commercially available instruments, of the kind offered by, for example, the companies Stem Corporation, Woodrolfe Road, Tollesbury, Essex, CM9 8SE, England, or H+P Labortechnik GmbH, Bruckmannring 28, 85764 Oberschleißheim, Germany. For the parallelized purification of compounds (I) or of intermediates produced during the preparation, there are available, inter alia, chromatography apparatuses, for example from ISCO, Inc., 4700 Superior Street, Lincoln, Nebr. 68504, USA. The apparatuses listed allow a modular procedure in which the individual process steps are automated, but between the process steps manual operations have to be carried out. This can be circumvented by using partly or completely integrated automation systems in which the respective automation modules are operated, for example, by robots. Automation systems of this type can be acquired, for example, from Zymark Corporation, Zymark Center, Hopkinton, Mass. 01748, USA.
Besides the methods described, the preparation of compounds of the formula (I) can take place completely or partially by solid-phase-supported methods. For this purpose, individual intermediates or all intermediates in the synthesis or a synthesis adapted for the corresponding procedure are bonded to a synthesis resin. Solid-phase-supported synthesis methods are described extensively in the specialist literature, for example: Barry A. Bunin in “The Combinatorial Index”, Verlag Academic Press, 1998.
The use of solid-phase-supported synthesis methods permits a number of protocols, which are known from the literature and which for their part may be performed manually or in an automated manner. For example, the so-called “tea bag method” (U.S. Pat. No. 4,631,211) in which products from IRORI, 11149 North Torrey Pines Road, La Jolla, Calif. 92037, USA, are employed, may be semiautomated. The automation of solid-phase-supported parallel syntheses is performed successfully, for example, by apparatuses from Argonaut Technologies, Inc., 887 Industrial Road, San Carlos, Calif. 94070, USA or MultiSynTech GmbH, Wullener Feld 4, 58454 Witten, Germany.
The preparation according to the processes described herein produces compounds of the formula (I) in the form of substance collections or libraries. Accordingly, the present invention also provides libraries of compounds of the formula (I) which comprise at least two compounds of the formula (I), and precursors thereof.
The present invention furthermore provides a method for controlling harmful plants and/or for regulating the growth of plants, characterized in that an effective amount
The present invention also provides a method for controlling unwanted plants, preferably in crops of useful plants, characterized in that an effective amount
The present invention furthermore also provides methods for regulating the growth of plants, preferably of useful plants, characterized in that an effective amount
In this context, the compounds according to the invention or the compositions according to the invention can be applied for example by pre-sowing (if appropriate also by incorporation into the soil), pre-emergence and/or post-emergence processes. Specific examples of some representatives of the monocotyledonous and dicotyledonous weed flora which can be controlled by the compounds of the invention are as follows, though there is no intention to restrict the enumeration to particular species.
In a method according to the invention for controlling harmful plants or for regulating the growth of plants, one or more compounds of the formula (I), (Ia) and/or salts thereof are preferably employed for controlling harmful plants or for regulating growth in crops of useful plants or ornamental plants, where in a preferred embodiment the useful plants or ornamental plants are transgenic plants.
The compounds of the formula (I) or (Ia) according to the invention and/or their salts are suitable for controlling the following genera of monocotyledonous and dicotyledonous harmful plants:
Monocotyledonous Harmful Plants of the Genera:
Aegilops, Agropyron, Agrostis, Alopecurus, Apera, Avena, Brachiaria, Bromus, Cenchrus, Commelina, Cynodon, Cyperus, Dactyloctenium, Digitaria, Echinochloa, Eleocharis, Eleusine, Eragrostis, Eriochloa, Festuca, Fimbristylis, Heteranthera, Imperata, Ischaemum, Leptochloa, Lolium, Monochoria, Panicum, Paspalum, Phalaris, Phleum, Poa, Rottboellia, Sagittaria, Scirpus, Setaria and Sorghum.
Dicotyledonous Harmful Plants of the Genera:
Abutilon, Amaranthus, Ambrosia, Anoda, Anthemis, Aphanes, Artemisia, Atriplex, Bellis, Bidens, Capsella, Carduus, Cassia, Centaurea, Chenopodium, Cirsium, Convolvulus, Datura, Desmodium, Emex, Erysimum, Euphorbia, Galeopsis, Galinsoga, Galium, Hibiscus, Ipomoea, Kochia, Lamium, Lepidium, Lindernia, Matricaria, Mentha, Mercurialis, Mullugo, Myosotis, Papaver, Pharbitis, Plantago, Polygonum, Portulaca, Ranunculus, Raphanus, Rorippa, Rotala, Rumex, Salsola, Senecio, Sesbania, Sida, Sinapis, Solanum, Sonchus, Sphenoclea, Stellaria, Taraxacum, Thlaspi, Trifolium, Urtica, Veronica, Viola and Xanthium.
When the compounds according to the invention are applied to the soil surface before germination of the harmful plants (weed grasses and/or broad-leaved weeds) (pre-emergence method), either the seedlings of the weed grasses or broad-leaved weeds are prevented completely from emerging or they grow until they have reached the cotyledon stage, but then stop growing and eventually, after three to four weeks have elapsed, die completely.
If the active ingredients are applied post-emergence to the green parts of the plants, growth stops after the treatment, and the harmful plants remain at the growth stage at the time of application, or they die completely after a certain time, such that competition by the weeds, which is harmful to the crop plants, is thus eliminated very early and in a lasting manner.
Although the compounds according to the invention display an outstanding herbicidal activity against monocotyledonous and dicotyledonous weeds, crop plants of economically important crops, for example dicotyledonous crops of the genera Arachis, Beta, Brassica, Cucumis, Cucurbita, Helianthus, Daucus, Glycine, Gossypium, Ipomoea, Lactuca, Linum, Lycopersicon, Miscanthus, Nicotiana, Phaseolus, Pisum, Solanum, Vicia, or monocotyledonous crops of the genera Allium, Ananas, Asparagus, Avena, Hordeum, Oryza, Panicum, Saccharum, Secale, Sorghum, triticale, triticum, Zea, are damaged only to an insignificant extent, or not at all, depending on the structure of the respective compound according to the invention and its application rate. For these reasons, the present compounds are very suitable for selective control of unwanted plant growth in plant crops such as agriculturally useful plants or ornamental plants.
In addition, the compounds according to the invention (depending on their particular structure and the application rate deployed) have outstanding growth-regulating properties in crop plants. They intervene in the plants' own metabolism with regulatory effect, and can thus be used for the controlled influencing of plant constituents and to facilitate harvesting, for example by triggering desiccation and stunted growth. Furthermore, they are also suitable for the general control and inhibition of unwanted vegetative growth without killing the plants in the process. Inhibition of vegetative growth plays a major role for many mono- and dicotyledonous crops since, for example, this can reduce or completely prevent lodging.
By virtue of their herbicidal and plant growth regulatory properties, the active ingredients can also be used to control harmful plants in crops of genetically modified plants or plants modified by conventional mutagenesis. In general, the transgenic plants are characterized by particular advantageous properties, for example by resistances to certain pesticides, in particular certain herbicides, resistances to plant diseases or pathogens of plant diseases, such as certain insects or microorganisms such as fungi, bacteria or viruses. Other specific characteristics relate, for example, to the harvested material with regard to quantity, quality, storability, composition and specific constituents. For instance, there are known transgenic plants with an elevated starch content or altered starch quality, or those with a different fatty acid composition in the harvested material.
It is preferred with a view to transgenic crops to use the compounds according to the invention and/or their salts in economically important transgenic crops of useful plants and ornamentals, for example of cereals such as wheat, barley, rye, oats, millet, rice and maize or else crops of sugar beet, cotton, soybean, oilseed rape, potato, tomato, peas and other vegetables.
It is preferred to employ the compounds according to the invention as herbicides in crops of useful plants which are resistant, or have been made resistant by recombinant means, to the phytotoxic effects of the herbicides.
By virtue of their herbicidal and plant growth regulatory properties, the active ingredients can also be used to control harmful plants in crops of genetically modified plants which are known or are yet to be developed. In general, the transgenic plants are characterized by particular advantageous properties, for example by resistances to certain pesticides, in particular certain herbicides, resistances to plant diseases or pathogens of plant diseases, such as certain insects or microorganisms such as fungi, bacteria or viruses. Other specific characteristics relate, for example, to the harvested material with regard to quantity, quality, storability, composition and specific constituents. For instance, there are known transgenic plants with an elevated starch content or altered starch quality, or those with a different fatty acid composition in the harvested material. Further special properties may be tolerance or resistance to abiotic stressors, for example heat, cold, drought, salinity and ultraviolet radiation.
Preference is given to the use of the compounds of the formula (I) according to the invention or salts thereof in economically important transgenic crops of useful plants and ornamental plants, for example of cereals such as wheat, barley, rye, oats, triticale, millet, rice, cassava and corn, or else crops of sugar beet, cotton, soybean, oilseed rape, potatoes, tomatoes, peas and other vegetables.
The compounds of the formula (I) can preferably be used as herbicides in crops of useful plants which are resistant, or have been made resistant by recombinant means, to the phytotoxic effects of the herbicides.
Conventional ways of producing novel plants which have modified properties in comparison to existing plants consist, for example, in traditional cultivation methods and the generation of mutants. Alternatively, novel plants with altered properties can be generated with the aid of recombinant methods.
A large number of molecular-biological techniques by means of which novel transgenic plants with modified properties can be generated are known to the person skilled in the art. For such recombinant manipulations, nucleic acid molecules which allow mutagenesis or sequence alteration by recombination of DNA sequences can be introduced into plasmids. With the aid of standard methods, it is possible, for example, to undertake base exchanges, remove parts of sequences or add natural or synthetic sequences. To connect the DNA fragments to each other, adapters or linkers may be added to the fragments.
For example, the generation of plant cells with a reduced activity of a gene product can be achieved by expressing at least one corresponding antisense RNA, a sense RNA for achieving a cosuppression effect, or by expressing at least one suitably constructed ribozyme which specifically cleaves transcripts of the abovementioned gene product.
To this end, it is firstly possible to use DNA molecules which encompass the entire coding sequence of a gene product inclusive of any flanking sequences which may be present, and also DNA molecules which only encompass portions of the coding sequence, in which case it is necessary for these portions to be long enough to have an antisense effect in the cells. It is also possible to use DNA sequences which have a high degree of homology to the coding sequences of a gene product, but are not completely identical to them.
When expressing nucleic acid molecules in plants, the protein synthesized may be localized in any desired compartment of the plant cell. However, to achieve localization in a particular compartment, it is possible, for example, to join the coding region to DNA sequences which ensure localization in a particular compartment. Such sequences are known to those skilled in the art (see, for example, Braun et al., EMBO J. 11 (1992), 3219-3227). The nucleic acid molecules can also be expressed in the organelles of the plant cells.
The transgenic plant cells can be regenerated by known techniques to give rise to entire plants. In principle, the transgenic plants may be plants of any desired plant species, i.e. not only monocotyledonous but also dicotyledonous plants.
Thus, transgenic plants can be obtained whose properties are altered by overexpression, suppression or inhibition of homologous (=natural) genes or gene sequences or expression of heterologous (=foreign) genes or gene sequences.
It is preferred to employ the compounds (I) according to the invention in transgenic crops which are resistant to growth regulators such as, for example, dicamba, or against herbicides which inhibit essential plant enzymes, for example acetolactate synthases (ALS), EPSP synthases, glutamine synthases (GS) or hydroxyphenylpyruvate dioxygenases (HPPD), or against herbicides from the group of the sulfonylureas, glyphosate, glufosinate or benzoylisoxazoles and analogous active ingredients.
When the active ingredients of the invention are used in transgenic crops, not only do the effects toward harmful plants which are observed in other crops occur, but often also effects which are specific to application in the particular transgenic crop, for example an altered or specifically widened spectrum of weeds which can be controlled, altered application rates which can be used for the application, preferably good combinability with the herbicides to which the transgenic crop is resistant, and influencing of growth and yield of the transgenic crop plants.
The invention therefore also relates to the use of the compounds of the formula (I) according to the invention and/or their salts as herbicides for controlling harmful plants in crops of useful plants or ornamentals, optionally in transgenic crop plants.
Preference is given to the use in cereals, here preferably maize, wheat, barley, rye, oats, millet or rice, by the pre- or post-emergence method.
Preference is also given to the use in soy beans by the pre- or post-emergence method.
The use according to the invention for the control of harmful plants or for growth regulation of plants also includes the case in which the active ingredient of the formula (I) or its salt is not formed from a precursor substance (“prodrug”) until after application on the plant, in the plant or in the soil.
The invention also provides the use of one or more compounds of the formula (I) or salts thereof or of a composition according to the invention (as defined below) (in a method) for controlling harmful plants or for regulating the growth of plants which comprises applying an effective amount of one or more compounds of the formula (I) or salts thereof onto the plants (harmful plants, if appropriate together with the useful plants), plant seeds, the soil in which or on which the plants grow or the area under cultivation.
The invention also provides a herbicidal or plant growth-regulating composition, characterized in that the composition
(a) comprises one or more compounds of the formula (I) and/or salts thereof as defined above, preferably one or more compounds of the formula (Ia) and/or salts thereof, in each case as defined above,
and
(b) one or more further substances selected from groups (i) and/or (ii):
(i) one or more further agrochemically active substances, preferably selected from the group consisting of insecticides, acaricides, nematicides, further herbicides (i.e. those not corresponding to the formula (I) defined above), fungicides, safeners, fertilizers and/or further growth regulators,
(ii) one or more formulation auxiliaries customary in crop protection.
A herbicidal or plant growth-regulating composition according to the invention comprises preferably one, two, three or more formulation auxiliaries (ii) customary in crop protection selected from the group consisting of surfactants, emulsifiers, dispersants, film-formers, thickeners, inorganic salts, dusting agents, carriers solid at 25° C. and 1013 mbar, preferably absorbent granulated inert materials, wetting agents, antioxidants, stabilizers, buffer substances, antifoam agents, water, organic solvents, preferably organic solvents miscible with water in any ratio at 25° C. and 1013 mbar.
The compounds (I) according to the invention can be used in the form of wettable powders, emulsifiable concentrates, sprayable solutions, dusting products or granules in the customary formulations. The invention therefore also provides herbicidal and plant growth-regulating compositions which comprise compounds of the formula (I) and/or salts thereof.
The compounds of the formula (I) and/or salts thereof can be formulated in various ways according to which biological and/or physicochemical parameters are required. Possible formulations include, for example: Wettable powders (WP), water-soluble powders (SP), water-soluble concentrates, emulsifiable concentrates (EC), emulsions (EW), such as oil-in-water and water-in-oil emulsions, sprayable solutions, suspension concentrates (SC), dispersions based on oil or water, oil-miscible solutions, capsule suspensions (CS), dusting products (DP), dressings, granules for scattering and soil application, granules (GR) in the form of microgranules, spray granules, absorption and adsorption granules, water-dispersible granules (WG), water-soluble granules (SG), ULV formulations, microcapsules and waxes.
These individual formulation types and the formulation assistants, such as inert materials, surfactants, solvents and further additives, are known to the person skilled in the art and are described, for example, in: Watkins, “Handbook of Insecticide Dust Diluents and Carriers”, 2nd ed., Darland Books, Caldwell N.J.; H. v. Olphen, “Introduction to Clay Colloid Chemistry”, 2nd ed., J. Wiley & Sons, N.Y.; C. Marsden, “Solvents Guide”, 2nd ed., Interscience, N.Y. 1963; McCutcheon's “Detergents and Emulsifiers Annual”, MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, “Encyclopedia of Surface Active Agents”, Chem. Publ. Co. Inc., N.Y. 1964; Schönfeldt, “Grenzflächenaktive Äthylenoxidaddukte” [Interface-active Ethylene Oxide Adducts], Wiss. Verlagsgesellschaft, Stuttgart 1976; Winnacker-Küchler, “Chemische Technologic” [Chemical Technology], volume 7, C. Hanser Verlag Munich, 4th Ed. 1986.
Wettable powders are preparations which can be dispersed uniformly in water and, in addition to the active ingredient, apart from a diluent or inert substance, also comprise surfactants of the ionic and/or nonionic type (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, polyoxyethylated fatty amines, fatty alcohol polyglycol ether sulfates, alkanesulfonates, alkylbenzenesulfonates, sodium lignosulfonate, sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodium dibutylnaphthalenesulfonate or else sodium oleoylmethyltaurate. To produce the wettable powders, the herbicidally active ingredients are finely ground, for example in customary apparatuses such as hammer mills, blower mills and air jet mills, and simultaneously or subsequently mixed with the formulation auxiliaries.
Emulsifiable concentrates are produced by dissolving the active ingredient in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene, or else relatively high-boiling aromatics or hydrocarbons or mixtures of the organic solvents, with addition of one or more ionic and/or nonionic surfactants (emulsifiers). Examples of emulsifiers which may be used are: calcium alkylarylsulfonates such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide-ethylene oxide condensation products, alkyl polyethers, sorbitan esters, for example sorbitan fatty acid esters, or polyoxyethylene sorbitan esters, for example polyoxyethylene sorbitan fatty acid esters.
Dustable powders are obtained by grinding the active ingredient with finely distributed solid substances, for example talc, natural clays such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.
Suspension concentrates may be water- or oil-based. They may be prepared, for example, by wet-grinding by means of commercial bead mills and optional addition of surfactants as have, for example, already been listed above for the other formulation types.
Emulsions, for example oil-in-water emulsions (EW), can be produced, for example, by means of stirrers, colloid mills and/or static mixers using aqueous organic solvents and optionally surfactants as already listed above, for example, for the other formulation types.
Granules can be prepared either by spraying the active ingredient onto adsorptive granular inert material or by applying active ingredient concentrates to the surface of carriers, such as sand, kaolinites or granular inert material, by means of adhesives, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils. Suitable active ingredients can also be granulated in the manner customary for the production of fertilizer granules—if desired as a mixture with fertilizers.
Water-dispersible granules are produced generally by the customary processes such as spray-drying, fluidized bed granulation, pan granulation, mixing with high-speed mixers and extrusion without solid inert material.
For the production of pan, fluidized-bed, extruder and spray granules, see e.g. processes in “Spray Drying Handbook” 3rd Ed. 1979, G. Goodwin Ltd., London, J. E. Browning, “Agglomeration”, Chemical and Engineering 1967, pages 147 ff, “Perry's Chemical Engineer's Handbook”, 5th Ed., McGraw Hill, New York 1973, p. 8-57.
For further details regarding the formulation of crop protection compositions, see, for example, G. C. Klingman, “Weed Control as a Science”, John Wiley and Sons, Inc., New York, 1961, pages 81-96 and J. D. Freyer, S. A. Evans, “Weed Control Handbook”, 5th Ed., Blackwell Scientific Publications, Oxford, 1968, pages 101-103.
The agrochemical preparations, preferably herbicidal or plant growth-regulating compositions, of the present invention preferably comprise a total amount of from 0.1 to 99% by weight, preferably 0.5 to 95% by weight, particularly preferably 1 to 90% by weight, especially preferably 2 to 80% by weight, of active ingredients of the formula (I) and their salts.
In wettable powders, the active ingredient concentration is, for example, about 10% to 90% by weight, the remainder to 100% by weight consisting of customary formulation constituents. In emulsifiable concentrates, the active ingredient concentration may be about 1% to 90% and preferably 5% to 80% by weight. Formulations in the form of dusts comprise 1% to 30% by weight of active ingredient, preferably usually 5% to 20% by weight of active ingredient; sprayable solutions contain about 0.05% to 80% by weight, preferably 2% to 50% by weight of active ingredient. In the case of water-dispersible granules, the active ingredient content depends partially on whether the active compound is present in liquid or solid form and on which granulation auxiliaries, fillers, etc., are used. In the water-dispersible granules, the content of active ingredient is, for example, between 1% and 95% by weight, preferably between 10% and 80% by weight.
In addition, the active ingredient formulations mentioned optionally comprise the respective customary stickers, wetters, dispersants, emulsifiers, penetrants, preservatives, antifreeze agents and solvents, fillers, carriers and dyes, defoamers, evaporation inhibitors and agents which influence the pH and the viscosity. Examples of formulation auxiliaries are described inter alia in “Chemistry and Technology of Agrochemical Formulations”, ed. D. A. Knowles, Kluwer Academic Publishers (1998).
The compounds of the formula (I) or salts thereof can be employed as such or in the form of their preparations (formulations) combined with other pesticidally active compounds, such as, for example, insecticides, acaricides, nematicides, herbicides, fungicides, safeners, fertilizers and/or growth regulators, for example as finished formulation or as tank mixes. The combination formulations can be prepared on the basis of the abovementioned formulations, while taking account of the physical properties and stabilities of the active ingredients to be combined.
Active ingredients which can be employed in combination with the compounds of formula (I) according to the invention in mixture formulations or in a tank mix are, for example, known active ingredients based on inhibition of, for example, acetolactate synthase, acetyl-CoA carboxylase, cellulose synthase, enolpyruvylshikimate-3-phosphate synthase, glutamine synthetase, p-hydroxyphenylpyruvate dioxygenase, phytoendesaturase, photosystem I, photosystem II, protoporphyrinogen oxidase, as described, for example, in Weed Research 26 (1986) 441-445 or “The Pesticide Manual”, 16th edition, The British Crop Protection Council and the Royal Soc. of Chemistry, 2012 and literature cited therein.
Of particular interest is the selective control of harmful plants in crops of useful plants and ornamentals. Although the compounds (I) according to the invention have already demonstrated very good to adequate selectivity in a large number of crops, in principle, in some crops and in particular also in the case of mixtures with other, less selective herbicides, phytotoxicities on the crop plants may occur. In this connection, combinations of compounds (I) according to the invention are of particular interest which comprise the compounds (I) or their combinations with other herbicides or pesticides and safeners. The safeners, which are used in an antidotically effective amount, reduce the phytotoxic side effects of the herbicides/pesticides employed, for example in economically important crops, such as cereals (wheat, barley, rye, corn, rice, millet), sugarbeet, sugarcane, oilseed rape, cotton and soybeans, preferably cereals.
The weight ratios of herbicide (mixture) to safener depend generally on the herbicide application rate and the efficacy of the safener in question and may vary within wide limits, for example in the range from 200:1 to 1:200, preferably 100:1 to 1:100, in particular 20:1 to 1:20. Analogously to the compounds (I) or mixtures thereof, the safeners can be formulated with further herbicides/pesticides and be provided and employed as a finished formulation or tank mix with the herbicides.
For application, the herbicide or herbicide/safener formulations present in commercial form are, if appropriate, diluted in a customary manner, for example in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules with water. Dust-type preparations, granules for soil application or granules for scattering and sprayable solutions are not normally diluted further with other inert substances prior to application.
The application rate of the compounds of the formula (I) and/or their salts is affected to a certain extent by external conditions such as temperature, humidity, etc. Here, the application rate may vary within wide limits. For the application as a herbicide for controlling harmful plants, the total amount of compounds of the formula (I) and their salts is preferably in the range from 0.001 to 10.0 kg/ha, with preference in the range from 0.005 to 5 kg/ha, more preferably in the range from 0.01 to 1.5 kg/ha, in particular in the range from 0.05 to 1 kg/ha. This applies both to application by the pre-emergence method and the post-emergence method, the pre-emergence treatment being preferred by virtue of the significantly higher activity.
When the compounds of the formula (I) and/or their salts are used as plant growth regulator, for example as culm stabilizer for crop plants like those mentioned above, preferably cereal plants, such as wheat, barley, rye, triticale, millet, rice or maize, the total application rate is preferably in the range of from 0.001 to 2 kg/ha, preferably in the range of from 0.005 to 1 kg/ha, in particular in the range of from 10 to 500 g/ha, very particularly in the range from 20 to 250 g/ha. This applies both to the pre-emergence and the post-emergence application.
The application as culm stabilizer may take place at various stages of the growth of the plants. Preferred is, for example, the application after the tillering phase, at the beginning of the longitudinal growth.
As an alternative, application as plant growth regulator is also possible by treating the seed, which includes various techniques for dressing and coating seed. Here, the application rate depends on the particular techniques and can be determined in preliminary tests.
The symbols “>” and “<” mean “greater than” and “smaller than”, respectively. The symbol “≥” means “greater than or equal to”, the symbol “≤” means “smaller than or equal to”.
If, in the context of the description and the examples, the designations “R” and “S” are stated for the absolute configuration at a center of chirality of the stereoisomers of the formulae (I) and (Ia), this follows the RS nomenclature of the Cahn-Ingold-Prelog rules.
The position of a substituent at a (phenyl) ring, for example in position 2 or position 3, is stated as a prefix to the symbol or the abbreviation of the radical, for example
2-Cl=2-chloro
2-Me=2-methyl
3-NO2=3-nitro
Numerations of the substituent positions for di- or trisubstituted substitution patterns are analogously stated as a prefix, for example
3,5-Me2=3,5-dimethyl (e.g. as substitution at the phenyl ring)
2,3,6-F3 or 2,3,6-F3=2,3,6-trifluoro (e.g. as substitution at the phenyl ring)
2,3-F2 or 2,3-F2=2,3-difluoro (e.g. as substitution at the phenyl ring)
Other abbreviations are to be understood analogously to the examples stated above.
“(R2)n═“H”=unsubstituted heteroaromatic radical Q (n=0)
“(R3)m═“H”=unsubstituted phenyl ring (m=0)
In addition, the customary chemical symbols and formulae apply, such as, for example, CH2 for methylene or CF3 for trifluoromethyl or OH for hydroxyl. Correspondingly, composite meanings are defined as composed of the abbreviations mentioned.
In an exemplary manner, some synthesis examples of compounds of the formula (I) are described below.
In the examples, the amounts (including the percentages) refer to the weight, unless stated otherwise.
Under protective gas (argon), 293 mg (2.612 mmol) of potassium tert-butoxide were added to 2.228 g (13.061 mmol) of methyl 3-(2,6-difluorophenyl)acrylate and 2.381 g (12.016 mmol) of (5-chloro-6-fluoropyridin-3-yl)acetonitrile in 20.0 ml of toluene and 2 ml of DMF, and the mixture was stirred at 60° C. for 20 h. After removal of the solvent under reduced pressure, the residue was taken up in ethyl acetate and washed twice with in each case 50 ml of water.

Physical data of some compounds according to the invention:
Test Methods:
1H-NMR data (CDCl3)—chemical shift of selected characteristic signals in ppm.
NMR Peak List Method
The 1H-NMR data of selected examples are noted in the form of 1H-NMR peak lists. For each signal peak, first the δ value in ppm and then the signal intensity in round brackets are listed. The pairs of δ value-signal intensity numbers for different signal peaks are listed with separation from one another by semicolons.
The peak list for one example therefore has the form:
δ1 (intensity1); δ2 (intensity2); . . . ; δi(intensityi); . . . ; δn (intensityn)
The intensity of sharp signals correlates with the height of the signals in a printed example of an NMR spectrum in cm and shows the true ratios of the signal intensities. In the case of broad signals, several peaks or the middle of the signal and the relative intensity thereof may be shown in comparison to the most intense signal in the spectrum.
Calibration of the chemical shift of 1H NMR spectra is accomplished using tetramethylsilane and/or the chemical shift of the solvent, particularly in the case of spectra which are measured in DMSO. Therefore, the tetramethylsilane peak may but need not occur in NMR peak lists.
The lists of the 1H-NMR peaks are similar to the classic 1H-NMR prints and thus usually comprise all peaks listed in classic NMR interpretations.
In addition, like classic 1H-NMR prints, they may show solvent signals, signals of stereoisomers of the target compounds, which are likewise part of the subject matter of the invention, and/or peaks of impurities.
When stating compound signals in the delta range of solvents and/or water, in our lists of 1H NMR peaks, the usual solvent peaks, for example peaks of DMSO in DMSO-D6 and the peak of water are shown, which usually have on average a high intensity.
The peaks of stereoisomers of the target compounds and/or peaks of impurities usually have a lower intensity on average than the peaks of the target compounds (for example with a purity of >90%).
Such stereoisomers and/or impurities may be typical of the particular preparation process. Their peaks can thus help in identifying reproduction of our preparation process with reference to “by-product fingerprints”.
An expert calculating the peaks of the target compounds by known methods (MestreC, ACD simulation, but also with empirically evaluated expected values) can, if required, isolate the peaks of the target compounds, optionally using additional intensity filters. This isolation would be similar to the relevant peak picking in classical 1H-NMR interpretation.
Further details of 1H NMR peak lists can be found in the Research Disclosure Database Number 564025.

Herbicidal Pre-Emergence Action
Seeds of monocotyledonous and dicotyledonous weed plants and crop plants were placed in wood-fiber pots in sandy loam and covered with soil. The compounds (I) according to the invention, formulated in the form of wettable powders (WP), were then applied as aqueous suspension or emulsion at a water application rate of 600 l/ha (converted) with the addition of 0.2% of wetting agent to the surface of the covering soil.
After the treatment, the pots were placed in a greenhouse and kept under good growth conditions for the test plants. After about 3 weeks, the effect was scored visually in comparison with untreated controls as percentages. For example, 100% activity=the plants have died, 50% herbicidal activity or damage=the plants have been reduced by 50% or the plant mass has been reduced by 50%, 0% activity=like control plants.
The results obtained show that compounds (I) according to the invention and their salts, in particular the compounds according to the invention characterized as preferred, have good to very good herbicidal activity against harmful plants at an application rate of 320 g or less per hectare, generally also even at a respective application rate of 80 g/ha.
The biological tests were carried out in each case separately with the compounds according to the invention below which, by virtue of the good to very good herbicidal activity thereof, are particularly preferred according to the invention:
Compound No. 1, 2, 3, 4, 5, 6, 14, 15, 85, 86, 186, 460, 461, 462, 463, 472, 543, 544, 1833, 1834, 1835, 1836, 1873, 1875, 1876, 1915, 1961, 1962, 1963, 1964, 2001, 2003, 2004, 2005, 2006 and 2043.
The biological tests were in each case carried out separately with the following compounds according to the invention: Compound No. 1 erythro+threo-1, 1 threo-2, 14 erythro-1+erythro-2, 14 threo-1, 14 threo-2, 15 erythro-1+erythro-2, 15 threo-1+threo-2, 460 erythro, 460 erythro-1, 460 threo, 460 threo-1, 460 threo-2, 472 erythro-1, 472 erythro-2, 472 threo-1, 472 threo-2, 6 erythro-2, 6 erythro-1, 6 threo-1, 6 threo-2 and 85 erythro.
Here, these compounds according to the invention were in each case employed in the biological tests as a component of a wettable powder (WP formulation).
At an application rate of 320 g/ha, all the compounds according to the invention mentioned showed 80% to 100% herbicidal activity in the biological tests, against one, more than one or all of the harmful plants below:
ALOMY=Alopecurus myosuroides
AVEFA=Avena fatua
CYPES=Cyperus esculentus
ECHCG=Echinochloa crus-galli
LOLMU=Lolium multiflorum
SETVI=Setaria viridis
ABUTH=Abutilon theophrasti
AMARE=Amaranthus retroflexus
POLCO=Polygonum convolvulus (=Fallopia convolvulus)
STEME=Stellaria media
VIOTR=Viola tricolor
VERPE=Veronica persica
What was determined was the respective herbicidal activity, in each case at the same point in time after application of the formulation in question, i.e. the damage to the respective harmful plant in %.
Furthermore, the compounds according to the invention mentioned above were applied to the following useful plants, in each case at the application rates mentioned.
ORYSA=Oryza sativa (common rice)
TRZAS=triticum aestivum (spring) (summer wheat)
ZEAMX=Zea mays (maize)
BRSNW=Brassica napus subsp. napus (winter) (winter oilseed rape)
Here, the observed damage to the respective useful plants was within the acceptable range and was generally assessed as low (generally in the range from 0 to 20%, mostly in the range from 0 to 10%).
Herbicidal Post-Emergence Action
Seeds of monocotyledonous and dicotyledonous weeds and crop plants were placed in sandy loam in wood-fiber pots, covered with soil and cultivated in a greenhouse under good growth conditions. 2 to 3 weeks after sowing, the test plants were treated at the one-leaf stage, where the compounds according to the invention, formulated in the form of wettable powders (WP), were applied by spraying as aqueous suspension or emulsion at a water application rate of 600 l/ha (converted) with the addition of 0.2% of wetting agent to the green parts of the plants. After the test plants had been kept in the greenhouse under optimum growth conditions for about 3 weeks, the activity of the preparations was rated visually in comparison to untreated controls in percent (%). For example, 100% activity=the plants have died, 50% herbicidal activity or damage=the plants have been reduced by 50% or the plant mass has been reduced by 50%, 0% activity=like control plants.
