Patent Application

The invention relates to the technical field of crop protection agents, in particular that of herbicides for the selective control of broad-leaved weeds and weed grasses in crops of useful plants.
Specifically, the present invention relates to substituted heteroarylpyrrolones and salts thereof, to processes for their preparation and to their use as herbicides.
In their application, crop protection agents known to date for the selective control of harmful plants in crops of useful plants or active compounds 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 compound is not wide enough, (c) that their selectivity in crops of useful plants is too low and/or (d) that they have a toxicologically unfavourable profile. Furthermore, some active compounds 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 compounds 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 compounds, the activity is too highly dependent on environmental conditions, such as weather and soil conditions.
The herbicidal activity of these known compounds, in particular at low application rates, and/or their compatibility with crop plants remain deserving of improvement.
Various documents describe substituted pyrrolones and hydantoins having herbicidal properties. WO2016/071359 and WO2016/071360 disclose pyrrolones carrying heterocyclic substituents at the nitrogen including, for example, isoxazolines which are optionally substituted further. Furthermore, substituted pyrrolones and their herbicidal or pesticidal properties are described in CH633678, DE 2735841, DE, EP0297378, EP0334133, EP0339390 and EP0286816. Additionally, WO2016/071361, WO2016/071362, WO2016/071363 and WO2016/071364 describe substituted hydantoins which also carry heterocyclic substituents at the nitrogen, for example isoxazolines which are optionally substituted further. Selected specifically substituted 1,3,4-thiadiazolyl- and 1,2,4-thiadiazolyl-2,5-dioxoimidazolines and their herbicidal action are described in DE2247266. Substituted pyrazolylpyrrolones and their use as herbicidally active compounds are described, for example, in WO2015/018434.
Furthermore, it is known that certain substituted carbamoyloxypyrrolones and phenyloxypyrrolones can be employed as growth regulators or germination stimulators (cf. WO2014/131843 and WO2015/128321). The structural motive of the hydroxypyrrolones is also found in substances isolated from Lilium candidum, for example 1,5-dihydro-5-hydroxy-3,4′-dimethyl-[1,2′-bi-2H-pyrrolo]-2,5′(1′H)-dione (cf. Ceska a Slovenska Farmacie, 2007, 56, 27; Neoplasma, 2000, 47, 313).
However, the use of heteroarylpyrrolones monosubstituted at the C═C double bond or of salts thereof as herbicidally active compounds has hitherto not been described. Surprisingly, it has now been found that heteroarylpyrrolones monosubstituted at the C═C double bond or salts thereof are particularly suitable as herbicides.
Accordingly, the present invention provides substituted heteroarylpyrrolones of the general formula (I) or salts thereof
in which
The compounds of the general formula (I) can form salts by addition of a suitable inorganic or organic acid, for example mineral acids, for example HCl, HBr, H2SO4, H3PO4 or HNO3, or organic acids, for example carboxylic acids such as formic acid, acetic acid, propionic acid, oxalic acid, lactic acid or salicylic acid or sulfonic acids, for example p-toluenesulfonic acid, onto a basic group, for example amino, alkylamino, dialkylamino, piperidino, morpholino or pyridino. In such a case, these salts will comprise the conjugated base of the acid as the anion. Suitable substituents in deprotonated form, for example sulfonic acids, particular sulfonamides or carboxylic acids, are capable of forming internal salts with groups, such as amino groups, which are themselves protonatable. Salts may also be formed by action of a base on compounds of the general formula (I). Suitable bases are, for example, organic amines such as trialkylamines, morpholine, piperidine and pyridine, and the hydroxides, carbonates and bicarbonates of ammonium, alkali metals or alkaline earth metals, especially sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate and potassium bicarbonate. These salts are compounds in which the acidic hydrogen is replaced by an agriculturally suitable cation, for example metal salts, especially alkali metal salts or alkaline earth metal salts, in particular sodium and potassium salts, or else ammonium salts, salts with organic amines or quaternary ammonium salts, for example with cations of the formula [NRaRbRcRd]+ in which Ra to Rd are each independently an organic radical, especially alkyl, aryl, arylalkyl or alkylaryl. Also suitable are alkylsulfonium and alkylsulfoxonium salts, such as (C1-C4)-trialkylsulfonium and (C1-C4)-trialkylsulfoxonium salts.
The substituted heteroarylpyrrolones of the formula (I) according to the invention can, depending on external conditions such as pH, solvent and temperature, be present in various tautomeric structures, all of which are embraced by the formula (I).
The compounds of the formula (I) used in accordance with the invention and salts thereof are referred to hereinafter as “compounds of the general formula (I)”.

The definitions of radicals listed above in general terms or within areas of preference apply both to the end products of the formula (I) and correspondingly to the starting materials or intermediates required for preparation in each case. These radical definitions can be combined with one another as desired, i.e. including combinations between the given preferred ranges.

Structural examples of heterocycles which are optionally substituted further are also listed below:
The heterocycles listed above are preferably substituted, for example, by hydrogen, halogen, alkyl, haloalkyl, hydroxyl, alkoxy, cycloalkoxy, aryloxy, alkoxyalkyl, alkoxyalkoxy, cycloalkyl, halocycloalkyl, aryl, arylalkyl, heteroaryl, heterocyclyl, alkenyl, alkylcarbonyl, cycloalkylcarbonyl, arylcarbonyl, heteroarylcarbonyl, alkoxycarbonyl, hydroxycarbonyl, cycloalkoxycarbonyl, cycloalkylalkoxycarbonyl, alkoxycarbonylalkyl, arylalkoxycarbonyl, arylalkoxycarbonylalkyl, alkynyl, alkynylalkyl, alkylalkynyl, trisalkylsilylalkynyl, nitro, amino, cyano, haloalkoxy, haloalkylthio, alkylthio, hydrothio, hydroxyalkyl, oxo, heteroarylalkoxy, arylalkoxy, heterocyclylalkoxy, heterocyclylalkylthio, heterocyclyloxy, heterocyclylthio, heteroaryloxy, bisalkylamino, alkylamino, cycloalkylamino, hydroxycarbonylalkylamino, alkoxycarbonylalkylamino, arylalkoxycarbonylalkylamino, alkoxycarbonylalkyl(alkyl)amino, aminocarbonyl, alkylaminocarbonyl, bisalkylaminocarbonyl, cycloalkylaminocarbonyl, hydroxycarbonylalkylaminocarbonyl, alkoxycarbonylalkylaminocarbonyl, arylalkoxycarbonylalkylaminocarbonyl.
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.
In the case of a partially or fully saturated nitrogen heterocycle, this may be joined to the remainder of the molecule either via carbon or via the nitrogen.
Suitable substituents for a substituted heterocyclic radical are the substituents specified further down, and additionally also oxo and thioxo. The oxo group as a substituent on a ring carbon atom is then, for example, a carbonyl group in the heterocyclic ring. As a result, lactones and lactams are preferably also included. The oxo group may also occur on the ring heteroatoms, which may exist in different oxidation states, for example in the case of N and S, and in that case form, for example, the divalent —N(O)—, —S(O)— (also SO for short) and —S(O)2— (also SO2 for short) groups in the heterocyclic ring. In the case of —N(O)— and —S(O)— groups, both enantiomers in each case are included.
According to the invention, the expression “heteroaryl” refers to heteroaromatic compounds, i.e. fully unsaturated aromatic heterocyclic compounds, preferably 5- to 7-membered rings having 1 to 4, preferably 1 or 2, identical or different heteroatoms, preferably O, S or N.

The term “halogen” denotes, for example, fluorine, chlorine, bromine or iodine. If the term is used for a radical, “halogen” denotes, for example, a fluorine, chlorine, bromine or iodine atom.
According to the invention, “alkyl” denotes a straight-chain or branched open-chain, saturated hydrocarbon radical which is optionally mono- or polysubstituted, and in the latter case is referred to as “substituted alkyl”. Preferred substituents are halogen atoms, alkoxy, haloalkoxy, cyano, alkylthio, haloalkylthio, amino or nitro groups, particular preference being given to methoxy, methyl, fluoroalkyl, cyano, nitro, fluorine, chlorine, bromine or iodine. The prefix “bis” also includes the combination of different alkyl radicals, e.g. methyl(ethyl) or ethyl(methyl).
“Haloalkyl”, “-alkenyl” and “-alkynyl” respectively denote alkyl, alkenyl and alkynyl partially or fully substituted by identical or different halogen atoms, for example monohaloalkyl such as CH2CH2C1, CH2CH2Br, CHClCH3, CH2C1, CH2F; perhaloalkyl such as CCl3, CClF2, CFCl2,CF2CClF2, CF2CClFCF3; polyhaloalkyl such as CH2CHFCl, CF2CClFH, CF2CBrFH, CH2CF3; the term perhaloalkyl also encompasses the term perfluoroalkyl.
“Partially fluorinated alkyl” denotes a straight-chain or branched, saturated hydrocarbon which is mono- or polysubstituted by fluorine, where the fluorine atoms in question may be present as substituents on one or more different carbon atoms of the straight-chain or branched hydrocarbon chain, for example CHFCH3, CH2CH2F, CH2CH2CF3, CHF2, CH2F, CHFCF2CF3.
“Partly fluorinated haloalkyl” denotes a straight-chain or branched, saturated hydrocarbon which is substituted by different halogen atoms with at least one fluorine atom, where any other halogen atoms optionally present are selected from the group consisting of fluorine, chlorine or bromine, iodine. The corresponding halogen atoms may be present as substituents on one or more different carbon atoms of the straight-chain or branched hydrocarbon chain. Partly fluorinated haloalkyl also includes full substitution of the straight or branched chain by halogen including at least one fluorine atom.
“Haloalkoxy” is, for example, OCF3, OCHF2, OCH2F, OCF2CF3, OCH2CF3 and OCH2CH2Cl; this applies correspondingly to haloalkenyl and other halogen-substituted radicals.
The expression “(C1-C4)-alkyl” mentioned here by way of example is a brief notation for straight-chain or branched alkyl having one to 4 carbon atoms according to the range stated for carbon atoms, i.e. encompasses the methyl, ethyl, 1-propyl, 2-propyl, 1-butyl, 2-butyl, 2-methylpropyl or tert-butyl radicals. General alkyl radicals with a larger specified range of carbon atoms, e.g. “(C1-C6)-alkyl”, correspondingly also encompass straight-chain or branched alkyl radicals with a greater number of carbon atoms, i.e. according to the example also the alkyl radicals having 5 and 6 carbon atoms.
Unless stated specifically, 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 hydrocarbyl radicals such as alkyl, alkenyl and alkynyl radicals, including in composite radicals.
Alkyl radicals, including in composite radicals such as alkoxy, haloalkyl, etc., are, for example, methyl, ethyl, n-propyl or i-propyl, n-, i-, t- or 2-butyl, pentyls, hexyls such as n-hexyl, i-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, where at least one double bond or triple bond is present.

If the compounds can form, through a hydrogen shift, tautomers whose structure is not formally covered by the formula (I), these tautomers are nevertheless covered by the definition of the inventive compounds of the formula (I), unless a particular tautomer is under consideration. For example, many carbonyl compounds may be present both in the keto form and in the enol form, both forms being encompassed by the definition of the compound of the formula (I).
Depending on the nature of the substituents and the manner in which they are attached, the compounds of the general formula (I) may be present as stereoisomers. The formula (I) embraces all possible stereoisomers defined by the specific three-dimensional form thereof, such as enantiomers, diastereomers, Z and E isomers. If, for example, one or more alkenyl groups are present, diastereomers (Z and E isomers) may occur. If, for example, one or more asymmetric carbon atoms are present, enantiomers and diastereomers may occur. Stereoisomers can be obtained from the mixtures obtained in the preparation by customary separation methods. The chromatographic separation can be effected either on the analytical scale to find the enantiomeric excess or the diastereomeric excess, or else on the preparative scale to produce test specimens for biological testing. It is likewise possible to selectively prepare stereoisomers by using stereoselective reactions with use of optically active starting materials and/or auxiliaries. The invention thus also relates to all stereoisomers which are embraced by the general formula (I) but are not shown in their specific stereomeric form, and to mixtures thereof.
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 below, they can be prepared by derivatization of other compounds (I).
Suitable isolation methods, purification methods and methods for separating stereoisomers of compounds of the formula (I) 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.
Synthesis of monosubstituted heteroarylpyrrolones of the general formula (I).
The monosubstituted heteroarylpyrrolones of the general formula (I) according to the invention can be prepared using known processes. The synthesis routes used and examined proceed from commercially available or easily preparable heteroaromatic amines and of correspondingly substituted furanones or furandiones. In the schemes which follow, the moieties Q, X, Y, W, R3 and R6 of the general formula (I) have the meanings defined above, unless exemplary, but not limiting, definitions are given. The first key intermediate prepared for the synthesis of the compounds of the general formula (I) is an optionally further-substituted heteroaromatic amine Q-NH2. By way of example, but not by way of limitation, this is illustrated by the synthesis of an optionally further-substituted 5-amino-1,2,4-isothiazole (III). To this end, a substituted nitrile is converted into the corresponding amidine (for example with ammonia) and, after halogenation with a suitable halogenating agent (for example sodium hypochlorite or bromine), converted into the desired 5-amino-1,2,4-isothiazole (IIIa) by reaction with potassium thiocyanate. Alternatively, bromochlorothiadiazole (IVa) can be prepared by amination, protection of the amino group (for example with (Boc)2O, where Boc represents tert-butyloxycarbonyl), subsequent transition metal-mediated coupling reaction (with a suitable transition metal catalyst such as PdCl2[PtBu2(p-NMe-Ph)]2) and subsequent acid-mediated deprotection (for example with trifluoroacetic acid=TFA) in a suitable polar-aprotic solvent (for example dichloromethane) (cf. WO2013/091539; Bioorg. Chem. 2014, 57, 90; Org. Lett. 2009, 11, 5666; WO2009/127546). Im Scheme 1 below, R4 has the meaning defined above.
The synthesis of a heteroaromatic amine Q-NH2 is furthermore described using the example of the preparation of optionally further-substituted amino-1,2,4-triazoles (cf. Scheme 2). To this end, by way of example, but not by way of limitation, a substituted orthoester is reacted with cyanamine, then cyclized with hydrazine and converted with N,N-dimethylformamide dimethyl acetal=DMF-DMA) into a protected amino-1,2,4-triazole which can then be converted at the ring nitrogen, using a suitable reagent (e.g. an alkyl iodide) into a suitable polar-aprotic solvent (e.g. N,N-dimethylformamide) into the corresponding N-substituted amino-1,2,4-triazole (IIIb). Alternatively, a suitable nitrotriazole (IVb) can be converted by substitution of the ring nitrogen and subsequent hydrogenation using a suitable transition metal catalyst (e.g. palladium or platinum on carbon) in a suitable solvent (e.g. acetic acid or dilute hydrochloric acid) into the desired N-substituted aminotriazole (IIIb) (cf. Synthesis 2003, 2001; Tetrahedron Lett. 2005, 46, 2469). In Scheme 2 below, R4 and R7 have the meanings defined above.
The synthesis of a heteroaromatic amine Q-NH2 can furthermore be described using the example of the preparation of optionally further-substituted aminopyrazoles (cf. Scheme 3). By reaction of an optionally substituted hydrazine or a corresponding hydrazine salt with a suitable, optionally further-substituted beta-ketonitrile (IVc) in a suitable solvent (e.g. ethanol) using a suitable base (e.g. potassium carbonate), it is possible to obtain optionally further-substituted aminopyrazoles (IIIc) (cf. J. Med. Chem. 2008, 51, 4672; J. Heterocyclic Chem. 1982, 19, 1267; WO2015/018434). In Scheme 3 below, R4, R5 and R7 have the meanings defined above.
Further intermediates are monosubstituted furan-2,5-diones (V), which can also be referred to as maleic anhydrides and which can be prepared by synthesis steps known from the literature (cf. J. Chem. Soc., Perkin Trans. 1, 1982, 215; EP1426365; J. Org. Chem. 1998, 63, 2646; WO2015/018431; Tetrahedron 2012, 68, 5863; Russian J. Org. Chem. 2007, 43, 801), for example compounds (V.1) and (V.2) in Scheme 4 below in a plurality of steps from a suitable acetylenedicarboxylic ester (VI). In Scheme 4 below, X by way of example, but not by way of limitation, in each case represents C—CH3 and C—C2H5, and Y by way of example, but not by way of limitation, represents C—H.
Monosubstituted heteroarylpyrrolones of the general formula (I) can be prepared in two steps by reacting a suitable optionally substituted heteroarylamine Q-NH2 (III) with a suitable optionally further-substituted maleic anhydride (V) using a suitable base (e.g. pyridine) in a suitable polar-aprotic solvent (e.g. acetonitrile) or under acidic conditions using a suitable acid (e.g. acetic acid or p-toluenesulfonic acid in toluene as solvent) and subsequent reduction of a carbonyl group of the substituted maleimide (II) formed. The reduction can be carried out in a suitable solvent (e.g. tetrahydrofuran and methanol) with the aid of a suitable reducing agent and can lead to regioisomers if X and Y are different. Suitable reducing agents are, for example, sodium hydride, lithium aluminum hydride, sodium borohydride or other hydrogen-producing metal hydrides. Alternatively, it is also possible to perform a transition metal-mediated hydrogenation (cf. CH633678, DE2247266, WO2015/018434). Since groups X and Y are different, the reduction of the carbonyl group can afford mixtures of regioisomers; accordingly, Scheme 4 below shows both possible regioisomers to illustrate this fact. In Scheme 4 below, X, Y and Q have the meanings defined above, R3, by way of example, but not by way of limitation, represents OH and R6, by way of example, but not by way of limitation, represents hydrogen. Furthermore, the general reaction sequence is described in Scheme 5 below by way of example, but not by way of limitation, using Q-13 and Q-23, where, in the case of Q-23, R4 in compounds of the general formula (I), by way of example, but not by way of limitation, represents methyl and where, in the case of Q-13, R4 of the general formula (I), by way of example, but not by way of limitation, represents tert-butyl, R5 of the general formula (I) represents methyl and R7 of the general formula (I) represents hydrogen. In each case, R1 of the general formula (I), by way of example, but not by way of limitation, represents methyl.
Alternatively, monosubstituted heteroarylpyrrolones of the general formula (Ia) can be prepared starting with the reaction of a hydroxy- or bromolactone (VII) with a suitable optionally substituted heteroarylamine Q-NH2 (III) in a suitable solvent (e.g. toluene) at elevated temperature. By further reaction of the resulting intermediate (VIII) with acetic anhydride using a suitable base (e.g. pyridine) at elevated temperature, the monosubstituted heteroarylpyrrolone of the general formula (IX) having an O-acetyl group is formed, which can be converted by heating under acidic conditions (e.g. in a mixture of acetic acid and water) into the corresponding monosubstituted heteroarylpyrrolone of the general formula (Ia) having a free OH group. In Scheme 6 below, X, Y and Q have the meanings defined above, R3 of the general formula (I), by way of example, but not by way of limitation, represents OH, OC(O)CH3 and R6 of the general formula (I), by way of example, but not by way of limitation, represents hydrogen.
If monosubstituted heteroarylpyrrolones of the general formula (I) have a free hydroxyl function, this can be acylated with suitable reagents (for example using a suitable carbonyl chloride and with the aid of a suitable base such as triethylamine in a suitable polar-aprotic solvent), sulfonylated (for example using a suitable sulfonyl chloride and with the aid of a suitable base such as triethylamine in a suitable polar-aprotic solvent), alkylated (for example using a suitable alkyl halide and with the aid of a suitable base such as potassium carbonate, cesium carbonate or sodium hydride in a suitable polar-aprotic solvent) or else into a carbonate (cf. WO2015/018434). In Scheme 7 below, X, Y and Q have the meanings defined above, R3 of the general formula (I), by way of example, but not by way of limitation, represents OH, OCH3, OSO2CH3, OC(O)CH3 and OC(O)OCH3, and R6 of the general formula (I), by way of example, but not by way of limitation, represents hydrogen. For better clarity, but not by way of limitation, in Scheme 7 below only one of the two possible regioisomers of the compounds of the general formula I is shown.

The 1H NMR data of selected examples are stated 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 δ value −signal intensity number pairs for different signal peaks are listed with separation from one another by semicolons.
Accordingly, the peak list of an example has the form: δ1 (intensity1); δ2 (intensity2); . . . ; δi (intensityi); . . . ; δn (intensityn) The intensity of sharp signals correlates with the height of the signals (in cm) in a printed example of an NMR spectrum 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. For calibration of the chemical shift of 1H NMR spectra, we use 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 conventional 1H NMR printouts and thus usually contain all peaks listed in a conventional NMR interpretation.
In addition, like conventional 1H NMR printouts, they may show solvent signals, signals of stereoisomers of the target compounds, which likewise form part of the subject-matter of the invention, and/or peaks of impurities. In the reporting of compound signals within the delta range of solvents and/or water, our lists of 1H NMR peaks show the standard solvent peaks, for example peaks of DMSO in DMSO-D6 and the peak of water, which usually have a high intensity on average. 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 conventional 1H NMR interpretation. Further details of 1H NMR peak lists can be found in the Research Disclosure Database Number 564025. Text ignore boxes

The present invention furthermore provides the use of one or more compounds of the formula (I) and/or salts thereof, as defined above, preferably in one of the embodiments identified as preferred or particularly preferred, in particular one or more compounds of the formulae (I.1) to (I.116) and/or salts thereof, in each case as defined above,
as herbicide and/or plant growth regulator, preferably in crops of useful plants and/or ornamental plants.
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
is applied to the (harmful) plants, seeds of (harmful) plants, the soil in which or on which the (harmful) plants grow or the area under cultivation.
The present invention also provides a method for controlling unwanted plants, preferably in crops of useful plants, characterized in that an effective amount
is applied to unwanted plants (for example harmful plants such as mono- or dicotyledonous weeds or unwanted crop plants), the seed of the unwanted plants (i.e. plant seeds, for example grains, seeds or vegetative propagation organs such as tubers or shoot parts with buds), the soil in which or on which the unwanted plants grow (for example the soil of crop land or non-crop land) or the area under cultivation (i.e. the area on which the unwanted plants will grow).
The present invention furthermore also provides methods for regulating the growth of plants, preferably of useful plants, characterized in that an effective amount
is applied to the plant, the seed of the plant (i.e. plant seed, for example grains, seeds or vegetative propagation organs such as tubers or shoot parts with buds), the soil in which or on which the plants grow (for example the soil of crop land or non-crop land) or the area under cultivation (i.e. the area on which the plants will grow).
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 according to 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) 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) according to the invention and/or their salts are suitable for controlling the following genera of monocotyledonous and dicotyledonous harmful plants:
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, Sorghum.
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, 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 compounds 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, so that in this manner competition by the weeds, which is harmful to the crop plants, is eliminated very early and in a sustained 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 of 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 compounds 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 corn 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 compounds 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 to herbicides which inhibit essential plant enzymes, for example acetolactate synthases (ALS), EPSP synthases, glutamine synthases (GS) or hydroxyphenylpyruvate dioxygenases (HPPD), or to herbicides from the group of the sulfonylureas, glyphosate, glufosinate or benzoylisoxazoles and analogous active compounds.
When the active compounds of the invention are employed in transgenic crops, not only do the effects toward harmful plants observed in other crops occur, but frequently 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 corn, wheat, barley, rye, oats, millet or rice, by the pre- or post-emergence method.
Preference is also given to the use in soybeans 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 compound 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 for 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 and/or plant growth-regulating composition, characterized in that the composition comprises
(a) one or more compounds of the formula (I) and/or salts thereof, as defined above, preferably in one of the embodiments identified as preferred or particularly preferred, in particular one or more compounds of the formulae (I.1) to (I.116) and/or salts thereof, in each case as defined above, and
(b) one or more further substances selected from groups (i) and/or (ii):
Here, the further agrochemically active substances of component (i) of a composition according to the invention are preferably selected from the group of substances mentioned in “The Pesticide Manual”, 16th edition, The British Crop Protection Council and the Royal Soc. of Chemistry, 2012.
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 adsorbant 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; Schonfeldt, “Grenzflächenaktive Äthylenoxidaddukte” [Interface-active Ethylene Oxide Adducts], Wiss. Verlagsgesellschaft, Stuttgart 1976; Winnacker-KUichler, “Chemische Technologie” [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 compound, 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 compounds 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 compound 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.
Dusting products are obtained by grinding the active compound with finely distributed solids, 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 produced either by spraying the active compound onto adsorptive granular inert material or by applying active compound 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 compounds 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 compounds of the formula (I) and their salts.
In wettable powders, the active compound 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 compound 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 compound, preferably usually 5% to 20% by weight of active compound; sprayable solutions contain about 0.05% to 80% by weight, preferably 2% to 50% by weight of active compound. In the case of water-dispersible granules, the active compound content depends partially on whether the active compound is in liquid or solid form and on which granulation auxiliaries, fillers, etc., are used. In the water-dispersible granules, the content of active compound is, for example, between 1% and 95% by weight, preferably between 10% and 80% by weight.
In addition, the active compound 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 used as such or in the form of their preparations (formulations) in a combination with other pesticidally active substances, for example insecticides, acaricides, nematicides, herbicides, fungicides, safeners, fertilizers and/or growth regulators, for example in the form of a finished formulation or of a tank mix. 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 compounds to be combined.
Active compounds 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 compounds 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 I.5 kg/ha, in particular preferably in the range from 0.05 to 1 kg/ha. This applies both to the pre-emergence and the post-emergence application.
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 corn, 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.
Active compounds which can be employed in combination with the compounds of the formula (I) according to the invention in compositions according to the invention (for example in mixed formulations or in the tank mix) are, for example, known active compounds which are based on the inhibition of, for example, acetolactate synthase, acetyl-CoA carboxylase, cellulose synthase, enolpyruvylshikimate-3-phosphate synthase, glutamine synthetase, p-hydroxyphenylpyruvate dioxygenase, phytoene desaturase, photosystem I, photosystem II, protoporphyrinogen oxidase, as are described in, for example, 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 the literature cited therein. Known herbicides or plant growth regulators which can be combined with the compounds according to the invention are, for example, the following active compounds, where the compounds are designated either with the “common name” in accordance with the International Organization for Standardization (ISO) or with the chemical name or with the code number. They always encompass all of the application forms such as, for example, acids, salts, esters and also all isomeric forms such as stereoisomers and optical isomers, even if not explicitly mentioned.

Seeds of monocotyledonous and dicotyledonous weeds and crop plants were placed in sandy loam in plastic or wood-fiber pots, covered with soil and cultivated in a greenhouse under controlled growth conditions. 2 to 3 weeks after sowing, the test plants were treated at the one-leaf stage. The compounds of the invention, formulated in the form of wettable powders (WP) or as emulsion concentrates (EC), were then sprayed onto the green parts of the plants as aqueous suspension or emulsion with addition of 0.5% additive at a water application rate of 600 l/ha (converted). 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. For example, 100% activity=the plants have died, 0% activity=like control plants.

Cooled fresh spinach leaves were comminuted and homogenized in 50 mM phosphate buffer, pH 6.8. 10 mM KCl, 0.34 M sucrose (sucrose buffer) (blender, 1 g of plant material/ml). The homogenate was subsequently filtered through 4 layers of Miracloth and the chloroplasts were isolated by centrifugation, i.e. 10 min of centrifugation at 4400×g (4° C.). The sediment was suspended in 25 ml of sucrose buffer and re-centrifuged for 10 min at 4400×g (4° C.). The sediment was then suspended in 40 ml of 50 mM phosphate buffer, pH 6.8, 10 mM KCl, without sucrose. In this step, the chloroplasts were osmotically ruptured and the thylakoid membranes were then obtained by centrifugation (10 min, 4400×g, 4° C.). The membrane sediment was finally suspended in about 20 ml of 50 mM phosphate buffer, pH 6.8, 10 mM KCl. Following protein determination and activity determination, the membrane suspension was divided into aliquots and frozen in liquid nitrogen. The aliquots were stored at −80° C. Under these conditions, the photosystem II preparation was storage stable for at least three months. The activity determination of photosystem II (PS II) was then carried out using the following test principle: The electron transfer from PS II to an artificial electron acceptor, 2,6-dichlorophenolindophenol (DCPIP), was measured with exposure to light. The concentration of the blue oxidized form of DCPIP was determined spectrophotometrically at wavelength λ=595 nm. The enzyme-catalyzed reduction of DCPIP resulted in a colorless leuco form and thus in a decrease of the absorption at 595 nm in the reaction batch, which decrease was measured as a function of time. The activity determination was carried out in microtiter plates (96 cavities) in a reaction volume of 200 μl. Here, 155 μl of dilute membrane suspension were initially charged in 50 mM of phosphate buffer, pH 6.8, 10 mM KCl. Depending on the activity of the PS II preparation, the dilution was adjusted such that the measurement of the decrease in absorption (λ=595 nm) was linear for at least 10 min. In each case 5 μl solution of the test compounds of a concentration of 100 μM in DMSO were added to the enzyme suspension; controls contained 5 μl DMSO; the final concentration of DMSO in the reaction batch was thus 2.5% (v/v); this concentration had no adverse effect on the enzymatic activity. On each microtiter plate, a known PS II inhibitor, for example metribuzin, was used as standard, which allowed the quality of the PS II test to be assessed. The reaction was started by addition of 40 μl DCPIP solution (600 μM in distilled water); the final concentration of DCPIP was 120 μM. Measurement of absorption was carried out over a period of 10 min at 22° C. and with exposure to light. Using metribuzin as comparative substance, the results for the efficacy of the compounds of the general formula (I) at 100 μM are stated in the table below using the following classification: ++++ (inhibition≥90%), +++ (90%>inhibition≥70%), ++ (70%>inhibition≥50%), + (50%>inhibition≥30%).
Effects of selected compounds of the general formula (I) according to the following table E1:
Similar results were also achievable with further compounds of the general formula (I).
