Description

The invention relates to novel substituted, optically active aminotriazines having at least two asymmetrically substituted carbon atoms, to a process for their preparation and to their use as herbicides.

Substituted aminotriazines are already known from the (patent) literature (cf. U.S. Pat. No. 3,816,419, U.S. Pat. No. 3,932,167, EP-191 496, EP-273 328, EP-411 153/WO 90/09 378, WO 97/00 254, WO 97/08 156). However, these compounds—some of which also have asymmetrically substituted carbon atoms—have hitherto not attained any particular importance.

This invention, accordingly, provides the novel substituted, optically active aminotriazines having at least two asymmetrically substituted carbon atoms of the general formula (I)

in which

A represents a single bond or represents in each case straight-chain or branched alkanediyl or oxaalkanediyl having in each case up to 6 carbon atoms,

R 1 represents amino, represents formylamino or represents in each case optionally cyano-, halogen- or C 1 -C 4 -alkoxy-substituted alkylamino, dialkylamino, alkylcarbonylamino, N-alkyl-N-alkylcarbonylamino, alkoxycarbonylamino, N-alkyl-N-alkoxycarbonylamino, alkylaminoalkylideneamino or dialkylaminoalkylideneamino having in each case up to 6 carbon atoms in the alkyl groups or alkylidene groups,

R 2 represents hydrogen, halogen or optionally cyano-, halogen- or C 1 -C 4 -alkoxy-substituted alkyl having up to 6 carbon atoms,

R 3 represents hydrogen, halogen or optionally cyano-, halogen- or C 1 -C 4 -alkoxy-substituted alkyl having up to 6 carbon atoms, or together with R 2 represents optionally cyano-, halogen- or C 1 -C 4 -alkyl-substituted alkanediyl having 2 to 5 carbon atoms,

R 4 represents alkyl having up to 6 carbon atoms or represents cycloalkyl having 3 to 6 carbon atoms,

Y represents hydrogen, hydroxyl, mercapto, amino, cyano, halogen, or represents in each case optionally cyano-, halogen- or C 1 -C 4 -alkoxy-substituted alkyl, alkoxy, alkylcarbonyloxy, alkoxycarbonyloxy, alkylaminocarbonyloxy, dialkylaminocarbonyloxy, alkylthio, alkylamino or dialkylamino having in each case up to 6 carbon atoms in the alkyl groups, and

Z represents an optionally substituted monocyclic or bicyclic, carbocyclic or heterocyclic group from the group consisting of cyclopentyl, cyclohexyl, phenyl, naphthyl, tetralinyl, decalinyl, indanyl, indenyl, furyl, benzofuryl, di-hydrobenzofuryl, thienyl, benzothienyl, dihydrobenzothienyl, isobenzofuryl, dihydroisobenzofuryl, isobenzothienyl, dihydroisobenzothienyl, pyrrolyl, indolyl, isoindolyl, indolinyl, isoindolinyl, benzodioxolyl, oxazolyl, benzoxazolyl, thiazolyl, benzothiazolyl, benzimidazolyl, indazolyl, oxadiazolyl, thiadiazolyl, pyrazolyl, pyridinyl, pyrimidinyl, pyrazinyl, pyridazinyl, quinolyl, isoquinolyl, quinoxalinyl, cinnolinyl and phthalazinyl,

 where the possible substituents are in each case preferably selected from the group below:

hydroxyl, amino, cyano, nitro, carbamoyl, sulphamoyl, halogen, in each case optionally hydroxyl-, cyano- or halogen-substituted alkyl, alkoxy, alkylamino or dialkylamino having in each case 1 to 6 carbon atoms in the alkyl groups, in each case optionally halogen-substituted alkylcarbonyl, alkoxycarbonyl, alkylcarbonylamino, alkylaminocarbonyl, dialkylaminocarbonyl, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylsulphonylamino, alkylaminosulphonyl or dialkylaminosulphonyl having in each case 1 to 6 carbon atoms in the alkyl groups, in each case optionally hydroxyl-, cyano-, nitro-, halogen-, C 1 -C 4 -alkyl-, C 1 -C 4 -halogenoalkyl-, C 1 -C 4 -alkoxy- or C 1 -C 4 -halogenoalkoxy-substituted phenyl or phenoxy, and in each case optionally halogen-substituted methylenedioxy or ethylenedioxy,

 with the proviso that in each individual case R 2 , R 3 and Y are different from one another and that the substituents at the two carbon atoms to which R 2 and R 3 or R 4 are attached are configured as follows:

(a) R configuration at the carbon atom to which R 2 and R 3 are attached and R configuration at the carbon atom to which R 4 is attached (“R,R-diastereomers”),

(b) R configuration at the carbon atom to which R 2 and R 3 are attached and S configuration at the carbon atom to which R 4 is attached (“R,S-diastereomers”),

(c) S configuration at the carbon atom to which R 2 and R 3 are attached and R configuration at the carbon atom to which R 4 is attached (“S,R-diastereomers”),

(d) S configuration at the carbon atom to which R 2 and R 3 are attached and S configuration at the carbon atom to which R 4 is attached (“S,S-diastereomers”),

(e) R configuration at the carbon atom to which R 2 and R 3 are attached and racemic configuration at the carbon atom to which R 4 is attached (“R,rac-diastereomers”),

(f) S configuration at the carbon atom to which R 2 and R 3 are attached and racemic configuration at the carbon atom to which R 4 is attached (“S,rac-diastereomers”).

Since the C atom to which R 2 , R 3 and Y are attached is not present in racemic form, all compounds according to the invention are optically active.

The novel substituted aminotriazines having at least two asymmetrically substituted carbon atoms of the general formula (I) are obtained when substituted biguanides of the general formula (II)

in which

A, R 1 , R 4 and Z are as defined above,

—and/or acid adducts of compounds of the general formula (II)— are reacted with (optically active) carboxylic acid derivatives of the general formula (III)

in which

R 2 , R 3 and Y are as defined above and

X represents halogen or alkoxy,

if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent,

and, if appropriate, further conversions within the scope of the above definition of the substituents are carried out by customary methods on the resulting compounds of the general formula (I).

The compounds of the general formula (I) can be converted by customary methods into other compounds of the general formula (I) according to the above definition of the substituents, for example by acylation of compounds of the formula (I) in which R 1 represents amino and/or Y represents hydroxyl, for example using acetyl chloride or propionyl chloride, or, for example, by fluorination of compounds of the formula (I) in which Y represents hydroxyl, for example using diethylaminosulphur tri-fluoride (“DAST”)—cf. the Preparation Examples.

The novel substituted aminotriazines having at least two asymmetrically substituted carbon atoms of the general formula (I) have strong and selective herbicidal activity. To a certain extent, they also have fungicidal and insecticidal activity.

In the definitions, the hydrocarbon chains, such as in alkyl, are in each case straight-chain or branched—including in combination with heteroatoms, such as in alkoxy or alkylthio.

The starting materials of the general formula (III) are known and/or can be prepared by processes known per se (cf. J. Chem. Soc. Perkin Trans. I, 1979, 2248-2252; Preparation Examples).

The process according to the invention for preparing the compounds of the general formula (I) is preferably carried out using a reaction auxiliary. Suitable reaction auxiliaries for the process according to the invention are, in general, the customary inorganic or organic bases or acid acceptors. These preferably include alkali metal or alkaline earth metal acetates, amides, carbonates, bicarbonates, hydrides, hydroxides or alkoxides, such as, for example, sodium acetate, potassium acetate or calcium acetate, lithium amide, sodium amide, potassium amide or calcium amide, sodium carbonate, potassium carbonate or calcium carbonate, sodium bicarbonate, potassium bicarbonate or calcium bicarbonate, lithium hydride, sodium hydride, potassium hydride or calcium hydride, lithium hydroxide, sodium hydroxide, potassium hydroxide or calcium hydroxide, sodium methoxide, ethoxide, n- or i-propoxide, n-, i-, s- or t-butoxide or potassium methoxide, ethoxide, n- or i-propoxide, n-, i-, s- or t-butoxide; furthermore also basic organic nitrogen compounds, such as, for example, trimethylamine, triethylamine, tripropylamine, tributylamine, ethyldiisopropylamine, N,N-dimethylcyclohexylamine, dicyclohexylamine, ethyl-dicyclohexylamine, N,N-dimethylaniline, N,N-dimethylbenzylamine, pyridine, 2-methyl-, 3-methyl-, 4-methyl-, 2,4-dimethyl-, 2,6-dimethyl-, 3,4-dimethyl- and 3,5-dimethyl-pyridine, 5-ethyl-2-methyl-pyridine, 4-dimethylamino-pyridine, N-methyl-piperidine, 1,4-diaza-bicyclo[2,2,2]octane (DABCO), 1,5-diazabicyclo[4,3,0]non-5-ene (DBN), or 1,8-diazabicyclo[5,4,0]undec-7-ene (DBU).

The process according to the invention for preparing the compounds of the general formula (I) is preferably carried out using a diluent. Suitable diluents for carrying out the process according to the invention are especially inert organic solvents. These include, in particular, aliphatic, alicyclic or aromatic, optionally halogenated hydrocarbons, such as, for example, benzine, benzene, toluene, xylene, chlorobenzene, dichlorobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, chloroform, carbon tetrachloride; ethers, such as diethyl ether, diisopropyl ether, dioxane, tetrahydrofuran or ethylene glycol dimethyl ether or ethylene glycol diethyl ether; ketones, such as acetone, butanone or methyl isobutyl ketone; nitriles, such as acetonitrile, propionitrile or butyronitrile; amides, such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methylformanilide, N-methylpyrrolidone or hexamethylphosphoric triamide; esters such as methyl acetate or ethyl acetate; sulphoxides, such as dimethyl sulphoxide; alcohols, such as methanol, ethanol, n- or i-propanol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, mixtures thereof with water or pure water.

When carrying out the process according to the invention, the reaction temperatures can be varied within a relatively wide range. In general, the process is carried out at temperatures between 0° C. and 150° C., preferably between 10° C. and 100° C.

The process according to the invention is generally carried out under atmospheric pressure. However, it is also possible to carry out the process according to the invention under elevated or reduced pressure—in general between 0.1 bar and 10 bar.

For carrying out the process according to the invention, the starting materials are generally employed in approximately equimolar amounts. However, it is also possible to use a relatively large excess of one of the components. The reaction is generally carried out in a suitable diluent in the presence of a reaction auxiliary, and the reaction mixture is generally stirred for several hours at the required temperature. Work-up is carried out by customary methods (cf. the Preparation Examples).

The active compounds according to the invention can be used as defoliants, desiccants, haulm killers and, especially, as weed killers. By weeds in the broadest sense there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledonous weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus, Taraxacum.

Dicotyledonous crops of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis, Cucurbita.

Monocotyledonous weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus, Apera.

Monocotyledonous crops of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus, Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

Depending on the concentration, the compounds are suitable for total weed control, for example on industrial terrain and rail tracks and on paths and areas with or without tree growth. Equally, the compounds can be employed for controlling weeds in perennial crops, for example forests, ornamental tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hop fields, on lawns and turf and pastures and for selective weed control in annual crops.

The compounds of the formula (I) according to the invention are particularly suitable for selective control of monocotyledonous and dicotyledonous weeds in monocotyledonous and dicotyledonous crops, both by the pre-emergence and by the post-emergence method.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspo-emulsion concentrates, natural and synthetic substances impregnated with active compound, and microencapsulations in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is to say liquid solvents and/or solid carriers, optionally with the use of surfactants, that is to say emulsifiers and/or dispersants and/or foam formers.

If the extender used is water, it is also possible to use, for example, organic solvents as auxiliary solvents. Liquid solvents which are mainly suitable are: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol, and also their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and water.

Suitable solid carriers are: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates; suitable solid carriers for granules are: for example crushed and fractionated natural rocks, such as calcite, marble, pumice, sepiolite, dolomite and synthetic granules of inorganic and organic meals, and granules of organic material, such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and protein hydrolysates; suitable dispersants are: for example lignosulphite waste liquors and methylcellulose.

Tackifiers, such as carboxymethylcellulose, natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, and also natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids can be used in the formulations. Other possible additives are mineral and vegetable oils.

It is possible to use colorants, such as inorganic pigments, for example iron oxide, titanium oxide, Prussian blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

A mixture with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellents, plant nutrients and agents which improve soil structure, is also possible.

The active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomizing, scattering.

The preparation and the use of the active compounds according to the invention can be seen from the examples below.

PREPARATION EXAMPLES

Example 1

At 20° C., a solution of 2.4 g (44 mmol) of sodium methoxide in 10 ml of methanol is added dropwise with stirring to a mixture of 9.7 g (40 mmol) of (S)-1-(1-phenyl-ethyl)-biguanide, 4.5 g (40 mmol) of ethyl (R)-lactate and 80 ml of methanol, and the reaction mixture is then stirred at room temperature (approximately 20° C.) for another 15 hours. The mixture is then diluted to about three times its original volume using approximately equivalent amounts by volume of methylene chloride and water, the mixture is shaken and the organic phase is then separated off, washed with water, dried with sodium sulphate and filtered. From the filtrate, the solvent is carefully distilled off under waterpump vacuum.

This gives 4.4 g (42% of theory) of 2-amino-4-(R)-(1-hydroxyethyl)-6-(S)-(1-phenyl-ethylamino)-1,3,5-triazine as an amorphousousous residue.

The log p values given in Table 1 were determined in accordance with EEC Directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) using a reversed phase column (C 18). Temperature: 43° C.

a) Mobile phases for the determination in the acidic range: 0.1% aqueous phosphoric acid, acetonitrile; linear gradient from 10% acetonitrile to 90% acetonitrile—the corresponding data in Table 1 are marked a)

b) mobile phases for the determination in the neutral range: 0.01 molar aqueous phosphate buffer solution, acetonitrile; linear gradient from 10% acetonitrile to 90% acetonitrile—corresponding data in Table 1 are marked b )

Calibration was carried out using unbranched alkan-2-ones (having 3 to 16 carbon atoms) with known log p values (determination of the log p values by the retention times using linear interpolation between two successive alkanones).

The lambda max values were determined using the UV spectra from 200 nm to 400 nm in the maxima of the chromatographic signals.

Starting Materials of the Formula (II)

Example (II-1)

At room temperature, 72 g of hydrochloric acid (33% strength) are added with stirring to a solution of 81 g (0.60 mol) of (S)-1-phenyl-ethylamine in 150 ml of methanol. The mixture is diluted with toluene to about three times its original volume and the volatile components are carefully distilled off under waterpump vacuum. After addition of 50.4 g (0.60 mol) of cyanoguanidine, the residue is fused at from 150° C. to 170° C. (internal temperature; bath temperature about 200° C.) for three hours.

This gives 142 g (98% of theory) of (S)-1-(1-phenyl-ethyl)-biguanide hydrochloride as a glass-like material which can be used without further purification for the reaction according to the process according to the invention (cf. Example 1).

The compound (S)-1-(1-phenyl-propyl)-biguanide hydrochloride can be prepared analogously to Example (II -1) starting from (S)-1-phenyl-propylamine.

Starting Materials of the Formula (III):

Example (III-1)

Step 1

Over a period of 15 minutes, 34.3 g (0.30 mol) of methanesulphonyl chloride are added a little at a time and with stirring to a solution, cooled with ice, of 27.9 g (0.29 mol) of methyl (R)-lactate in 100 ml of pyridine. The reaction mixture is stirred at 5° C. for two hours, and then added to 100 ml of water and the mixture is extracted three times within each case 100 ml of methyl t-butyl ether (MTBE). The combined MTBE, phases are washed with ice-cold 6N hydrochloric acid (2×100 ml), with water (2×100 ml) and with ice-cold sodium bicarbonate solution (3×100 ml), dried with sodium sulphate and filtered. The filtrate is stirred with activated carbon (Norit A) for 30 minutes and filtered once more. From the filtrate, the solvent is carefully distilled off under waterpump vacuum.

This gives methyl (R)-α-methylsulphonyloxy-propionate as an amorphous residue which can be reacted without further purification according to the description of step 2 (below).

Step 2

With stirring, 18.8 g (0.32 mol) of potassium fluoride are added to a mixture, heated to 125° C., of 47.9 g (0.26 mol) of methyl (R)-α-methylsulphonyloxy-propionate and 250 g of acetamide. 8 ml of a 1 molar solution of tetrabutylammonium fluoride in tetrahydrofuran are then added dropwise to the mixture. The reaction mixture is then stirred at 125° C. for 5 hours and at room temperature (approximately 20° C.) for 15 hours, then heated to 90° C. and admixed with vigorous stirring with 250 ml of water. After cooling to room temperature, the mixture is extracted three times with in each case 250 ml of dichloromethane. The combined organic phases are washed with saturated aqueous sodium chloride solution (2×100 ml) and then with water (1×100 ml), dried with sodium sulphate and filtered. The filtrate is stirred with activated carbon for 30 minutes and filtered once more. From the filtrate, the solvent is then carefully distilled off under waterpump vacuum. This gives methyl (S)-α-fluoro-propionate as an amorphous residue which can be used without further purification for the reaction according to the process according to the invention (cf. Example 1).

The compound methyl (R)-α-fluoro-propionate can be prepared analogously to Example (III-1) starting from methyl (S)-lactate.
