Description

The present invention relates to novel 4-(4-tert-butylphenyl)cyclohexylamines and acid-addition salts and quaternary salts thereof, to a process and intermediates for the preparation thereof, to the use thereof as fungicides, to fungicides, and to a method of controlling harmful fungi using these active ingredients.

The compound trans-4-tert-butyl-N-benzylcyclohexylamine is known (J. Org. Chem. 48 (1983) 3412-3422), but nothing is known on its fungicidal action

4-(Cyclohexylmethyl)cyclohexylamine and its N,N-dimethyl derivative are known as fungicides (U.S. Pat. No. 3,981,766), but their fungicidal action is unsatisfactory.

1-[4-(4-tert-Butylphenyl)cyclohexyl]-2,6-dimethylmorpholine has been described as a fungicide (EP 259 977), but its efficacy is poor in some areas of application, in particular at low application rates and concentrations.

Fungicidal cyclohexylamines are disclosed in DE 36 40 247. Their fungicidal action is good, but their plant compatibility is unsatisfactory, particularly at relatively high application rates.

We have now found that 4-(4-tert-butylphenyl)cyclohexylamines and the quaternary ammonium salts thereof, of the formulae ##STR2## where R.sup.1 is hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.3 -C.sub.6 -alkenyl,

R.sup.2 is, for example, straight-chain or branched C.sub.1 -C.sub.12 -alkyl, in particular C.sub.1 -C.sub.4 -alkyl, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-pentyl, isopentyl, neopentyl, n-hexyl, neohexyl, n-heptyl, n-octyl, 2-ethylhexyl, n-nonyl, n-decyl, n-undecyl or n-dodecyl; C.sub.1 -C.sub.12 -haloalkyl such as chloromethyl, bromomethyl, iodomethyl, 2-chloroethyl, 4-chloro-1-butyl, 3-chloro-1-butyl-, 3-chloro-2-methyl-1-propyl, 5-chloro-1-pentyl or 6-chloro-1-hexyl; C.sub.1 -C.sub.12 -hydroxyalkyl, such as 2-hydroxyethyl, 2-hydroxy-1-propyl, 6-hydroxy-1-hexyl, 8-hydroxy-1-octyl or 10-hydroxy-1-decyl; C.sub.3 -C.sub.12 -cycloalkyl such as cyclopropyl, cyclobutyl, cyclopentyl, oyclohexyl, cycloheptyl, cyclodecyl or cyclododecyl; C.sub.4 -C.sub.12 -alkylcycloalkyl such as methylcyclopropyl, methylcyclopentyl, 2-, 3- or 4-methylcyclohexyl, 2-, 3- or 4-ethylcyclohexyl, 4-isopropylcyclohexyl, 4-tert-butylcyclohexyl, 2,2-, 3,3- or 4,4-dimethylcyclohexyl, 2,6-dimethylcyclohexyl or 3,3,5,5-tetramethylcyclohexyl; C.sub.7 -C.sub.12 -bicycloalkyl such as bicyclo[2.2.1]hept-2-yl, 1,7,7-trimethylbicyclo[2.2.1]hept-2-yl, bicyclo[4.4.0]dec-2-yl or bicyclo[4.4.0]dec-3-yl; phenyl, C.sub.1 -C.sub.4 -alkylphenyl, mono-, di- or trimethylphenyl, ethylphenyl, isopropylphenyl, tert-butylphenyl, C.sub.1 -C.sub.4 -alkoxyphenyl, mono-, di- or trimethoxyphenyl, n- or tertphenyl, C.sub.1 -C.sub.4 -haloalkylphenyl, C.sub.1 -C.sub.4 -haloalkoxybutoxy phenyl, trifluoromethylphenyl, difluoromethoxyphenyl, trifluoromethoxyphenyl, tetrafluoroethoxyphenyl, cyanophenyl, nitrophenyl, mono-, di- or trichlorophenyl, mono-, di- or trifluorophenyl, chlorofluorophenyl, bromophenyl, aryl(C.sub.1 -C.sub.3)alkyl, such as benzyl, C.sub.1 -C.sub.4 -alkylbenzyl, mono-, di- or trimethylbenzyl, tert-butylbenzyl, halobenzyl, fluorobenzyl, mono-, di- or trichlorobenzyl, C.sub.1 -C.sub.4 -alkoxybenzyl, mono-, di- or trimethoxybenzyl, cyanobenzyl, nitrobenzyl, 2-phenylethyl, 2-(methoxyphenyl)ethy1,2-(chlorophenyl)ethy1,2-(fluorophenyl)ethyl, 2-(tert-butylphenyl)ethyl, 3-phenylpropyl, 3-(chlorophenyl)propyl or 3-(fluorophenyl)propyl.

X.sup..crclbar. is an inorganic or organic acid anion, for example chloride, bromide, iodide, sulfate, hydrogen sulfate, phosphate, hydrogen phosphate, dihydrogen phosphate, nitrate, tetrafluoroborate; formate, acetate, oxalate, methanesulfonate, benzenesulfonate, p-toluenesulfonate or dodecylbenzenesulfonate.

Examples of acids for the preparation of the acid-addition salts are mineral acids, hydrochloric acid, sulfuric acid, nitric acid, formic acid, alkylcarboxylic acids, such as acetic acid, propionic acid, oxalic acid, sulfonic acids, such as methanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid and dodecylbenzenesulfonic acid.

The novel compounds of the formulae 1 and 2 can exist in two diastereomeric forms, namely as cis-1,4- and as trans-1,4-disubstituted cyclohexane Depending on the preparation method, they are obtained either as pure diastereomers or as diastereomer mixtures. If desired, the latter can be resolved to give pure diastereomers by generally known methods, for example by chromatography or fractional crystallization. The present invention relates both to the pure diastereomers and to mixtures thereof.

In some of the radicals R.sup.2 according to the invention, further isomers can occur in addition to the abovementioned cis/trans isomerism. Depending on the nature of R.sup.2, these isomers may be enantiomers or diastereomers. Here too, the diastereomeric compounds can be resolved by conventional methods, for example by chromatography or crystallization All isomeric compounds and mixtures thereof with one another are included in the present invention. The pure diastereomers or enantiomers and the mixtures thereof are suitable for use of the novel amines as fungicides Preference is given to

The present invention also relates to a process for the preparation of the novel amines of the formula 1.

a) These amines can be prepared, for example, by reacting an amine of the formula ##STR3## where R.sup.1 hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.3 -C.sub.6 -alkenyl and

R.sup.2 is C.sub.1 -C.sub.12 -alkyl, with the proviso that R.sup.1 and R.sup.2 are not simultaneously C.sub.1 -C.sub.4 -alkyl, or is C.sub.1 -C.sub.12 -haloalkyl, C.sub.1 -C.sub.12 -hydroxyalkyl, C.sub.3 -C.sub.12 -cycloalkyl, C.sub.4 -C.sub.12 -alkylcycloalkyl, C.sub.7 -C.sub.12 -bicycloalkyl, C.sub.3 -C.sub.12 -alkenyl, unsubstituted, monosubstituted, disubstituted or trisubstituted phenyl, or unsubstituted, monosubstituted, disubstituted or trisubstituted phenyl(C.sub.1 -C.sub.3)-alkyl, possible substituents being in each case identical or different C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -haloalkoxy, halogen, cyano, hydroxyl or nitro groups, with 4-(4-tert-butylphenyl)cyclohexanone, and reducing the imine (in the case where R.sup.1 is hydrogen) or enamine (in the case where R.sup.1 is not hydrogen) produced as a reaction product, either directly or after isolation, using a reducing agent to give an amine of the formula 1.

It is advantageous to remove from the reaction mixture the water of reaction liberated on reaction of an amine of the formula 3 in which R.sup.1 and R.sup.2 are as defined above with 4-(4-tert-butylphenyl)cyclohexanone. This can be effected, for example, by adding a dehydrating agent or by azeotropic distillation. Examples of suitable dehydrating agents are salts which are free of or low in water of hydration, such as sodium sulfate, magnesium sulfate, zinc sulfate, calcium chloride or molecular sieves. The reaction is carried out in the presence or absence of an inert organic solvent and in the presence or absence of a catalytic amount of acid. Suitable solvents are hydrocarbons, such as cyclohexane, benzene, toluene or xylenes, chlorinated hydrocarbons, such as dichloromethane or 1,2-dichloroethane, or ethers, such as diethyl ether, methyl tert-butyl ether, tetrahydrofuran or dioxane. Examples of suitable acids are mineral acids, such as sulfuric acid or phosphoric acid, or sulfonic acids, such as methanesulfonic acid, benzenesulfonic acid or p-toluenesulfonic acid. The amount of acid necessary is, for example, from 0 to 10 mol-%, preferably from 0 to 1 mol-%, based on the amine of the formula 3. The reaction can be carried out at room temperature or at elevated temperature, for example up to the boiling point of the particular solvent. If the reaction temperature which is necessary cannot be achieved under atmospheric pressure or if the reaction proceeds only slowly, the reaction can be carried out in an autoclave (with or without a solvent) at elevated temperature under the inherent pressure of the reaction mixture. If the water of reaction produced is removed from the reaction mixture by azeotropic distillation, the reaction is carried out at the boiling point of the particular solvent. Preferred solvents here are aromatic hydrocarbons, such as benzene, toluene or xylenes.

The unsaturated nitrogen compound (imine or enamine) produced on reaction of an amine of the formula 3 where R.sup.1 and R.sup.2 are as defined above with 4-(4-tertbutylphenyl)cyclohexanone can be reduced by conventional methods to give an amine of the formula 1. Specific examples of preferred reducing agents are hydrogen, formic acid, or complex hydrides such as sodium borohydride or sodium cyanoborohydride. Particular preference is given to hydrogen in the presence of a metallic catalyst. Examples of suitable catalysts are finely divided metals, such as Raney nickel or Raney cobalt, and noble metals, such as palladium or platinum, with or without a solid carrier. The hydrogenation using hydrogen can be carried out with or without pressure (cf., for example, Houben-Weyl, Methoden der Organischen Chemie, Volume 11/1, pp. 602 ff, G. Thieme Verlag, Stuttgart, 1957). It is occasionally advantageous to prepare the amine of the formula 1 in one step from an amine of the formula 3 and 4-(4-tert-butylphenyl)cyclohexanone.

A known process for this purpose in which the reducing agent is formic acid is the reductive amination by the Leuckardt-Wallach method (cf., for example, Houben-Weyl, Methoden der Organischen Chemie, Volume 11/1, pp. 648 ff, G. Thieme Verlag, Stuttgart, 1957). Another process, which is particularly advantageous for laboratory scale syntheses, uses sodium cyanoborohydride as the reducing agent (cf., for example, C. F. Lane, Synthesis 1975, 135). The combination of sodium cyanoborohydride and anhydrous zinc chloride has proven particularly expedient (cf. S. Kim et al., J. Org. Chem. 50 (1985) 1927).

In this process, the NaBH.sub.3 CN:ZnCl.sub.2 molar ratio can be, for example, from 1:2 to 1:0.5, preferably 1:0.5. As far as the amount of NaBH.sub.3 CN employed is concerned, either the amine component 3 or the ketone component can be used in an equimolar amount; an excess of the other component may occasionally be advantageous in order to accelerate or complete the reaction The reaction is preferably carried out in a lower alcohol, such as methanol, ethanol, n-propanol or isopropanol, particularly preferably in methanol, as solvent, at between 0.degree. C. and the boiling point of the particular solvent. The reaction is preferably carried out at room temperature.

The 4-(4-tert-butylphenyl)cyclohexanone used as starting material is novel. It can be prepared from known, commercially available 4-phenylcyclohexanone by Friedel-Crafts alkylation of the phenyl ring. Examples of alkylating agents are tert-butyl chloride or bromide, tert-butanol or 2-methylpropene (cf., for example, Houben-Weyl, Methoden der Organischen Chemie, Vol. 5/2b, pp. 154 ff., pp. 179 ff., G. Thieme Verlag, Stuttgart, 1981). Preference is given to 2-methylpropene in the presence of a mineral acid, for example sulfuric acid or phosphoric acid, or in the presence of a Lewis acid, such as aluminum trichloride, iron(III) chloride or boron trifluoride. Suitable solvents are in particular chlorinated hydrocarbons, especially dichloromethane, tetrachloromethane, and 1,2-dichloroethane. The tert-butylation of the 4-phenylcyclohexanone can be carried out at room temperature or below, preferably at from 0.degree. to 20.degree. C.

The amines of the formula 3 where R.sup.1 and R.sup.2 are as defined above are known compounds and those which are not commercially available can be prepared by known processes.

The amines prepared by the above-described process, where R.sup.1 and R.sup.2 are as defined above, are generally mixtures of the two possible stereoisomers containing a cis- or trans-1,4-disubstituted cyclohexane ring. These cis/trans mixtures may, if desired, be resolved into their constituents by known methods, for example by chromatography or fractional crystallization.

b) A further process allows the targeted preparation of cis- or trans-4-(4-tert-butylphenyl)cyclohexylamines of the formula 1 where

R.sup.1 is hydrogen and R.sup.2 is C.sub.1 -C.sub.12 -alkyl, C.sub.1 -C.sub.12 -haloalkyl, C.sub.1 -C.sub.12 -hydroxyalkyl, C.sub.3 -C.sub.12 -cycloalkyl, C.sub.4 -C.sub.12 -alkylcycloalkyl, C.sub.7 -C.sub.12 -bicycloalkyl, C.sub.3 -C.sub.12 -alkenyl, unsubstituted, monosubstituted, disubstituted or trisubstituted phenyl, or unsubstituted, monosubstituted, disubstituted or trisubstituted phenyl(C.sub.1 -C.sub.3)alkyl, possible substituents in each case being identical or different C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -haloalkoxy, halogen, cyano, hydroxyl or nitro groups

This process comprises first converting 4-(4-tert-butylphenyl)cyclohexanone into 4-(4-tert-butylphenyl)cyclohexanone oxime by conventional methods using hydroxylamine or a hydroxylamine salt, and subsequently reducing this oxime using sodium in ethanol (cf., for example, Chem. Ind. (London) 1972, 683). The trans-4-(tert-butylphenyl)cyclohexylamine obtained is then reacted in a further step with a carbonyl compound of the formula ##STR4## where R.sup.3 and R.sup.4 are such that the radical ##STR5## corresponds in its entirety to R.sup.2 as defined above, and the imine formed is reduced, directly or after isolation, using a reducing agent to give the amine of the formula 1.

If 4-(4-tert-butylphenyl)cyclohexanone oxime is reduced, for example, using hydrogen, a mixture of cis- and trans-4-(4-tert-butylphenyl)cyclohexylamine is obtained, which can be resolved into the pure cis- and trans-isomers by conventional methods, for example by chromatography, distillation or fractional crystallization of an acid-addition salt with subsequent liberation of the base The two isomers can then be reacted separately with a carbonyl compound of the formula ##STR6## R.sup.3 and R.sup.4 are as defined above to give the pure cis- where and trans-configured amines of the formula 1.

It is of course also possible to react the mixture of cis- and trans-4-(4-tert-butylphenyl)cyclohexylamines with a carbonyl compound of the formula 4 and to resolve the resultant isomer mixture of amines of the formula 1 into its constituents, for example by chromatography or crystallization.

A further way of preparing a cis/trans mixture of 4-(4-tert-butylphenyl)cyclohexylaminescomprises alkylating cis/trans-4-phenylcyclohexylamine using 2-methylpropene in the presence of an at least equimolar amount of mineral acid, for example sulfuric acid. Preferred solvents are chlorinated hydrocarbons, e.g. dichloromethane, tetrachloromethane or 1,2-dichloroethane. The alkylation can be carried out at room temperature or below, preferably at from 0.degree. to 20.degree. C.

The 4-phenylcyclohexylamine used as a starting material is known. It can be prepared, for example, by hydrogenating 4-aminobiphenyl (R. Egli, C.H. Eugster, Helv. Chim. Acta 58 (1975) 2321) or 4-phenylcyclohexanone oxime (Nightingale et al., J. Org. Chem. 17 (1952) 1017).

The carbonyl compounds of the formula 4 which are required for process b) are common chemicals, and those which are not commercially available can be prepared by conventional methods.

The reaction conditions described in detail for process a) also apply similarly to process b).

The above-described process b) gives the amines of the formula 1 where R.sup.1 is hydrogen. These secondary amines can, if desired, be converted into tertiary amines of the formula 1 where R.sup.1 is C.sub.1 -C.sub.6 -alkyl or C.sub.3 -C.sub.6 -alkenyl by known alkylation reactions.

If the alkylating agent used is a methyl compound of the formula

CH.sub.3 --A 5 where A is a nucleofugic leaving group, e.g. chlorine, bromine, iodine, O--SO.sub.2 --OCH.sub.3, O--SO.sub.2 --CH.sub.3 or O-SO.sub.2 --p--C.sub.6 H.sub.4 --CH.sub.3, and the alkylating agent is employed in excess, 4-(4-tert-butylphenyl)cyclohexylammonium salts of the formula 2 where R.sup.2 is as defined above are obtained

This quaternization can be carried out in the presence or absence of a diluent Examples of suitable diluents are alcohols, such as methanol, ethanol, n- or isopropanol, n-butanol or cyclohexanol, ethers, such as diethyl ether, methyl tert-butyl ether, tetrahydrofuran or dioxane, esters, such as methyl acetate or ethyl acetate, nitriles, such as acetonitrile or propionitrile, nitro compounds, such as nitromethane or nitrobenzene, or other solvents which are inert in this reaction The alkylation is preferably carried out using two to 6 times the molar amount of alkylating agent of the formula 5 and at from 20.degree. to 200.degree. C. The reaction is expediently carried out at the boiling point of the particular diluent, or, if none is used, of the particular alkylating agent.

It is occasionally advantageous to carry out the quaternization in the presence of an auxiliary base, which can be added in excess or in an equimolar amount, based on the amine 1 to be alkylated. The use of a base which is insoluble in the reaction medium, for example sodium carbonate, potassium carbonate or calcium carbonate, is particularly advantageous

The reaction product obtained is a 4-(4-tertbutylphenyl)cyclohexylammonium salt of the formula ##STR7## where R.sup.2 and A are as defined above. If necessary, the anion A.sup..crclbar. can be replaced by another, plant-compatible acid anion by conventional methods, for example by ion exchange chromatography. ##STR8##

In general terms, the novel compounds are extremely effective on a broad spectrum of phytopathogenic fungi, in particular those from the class consisting of the Ascomycetes and Basidiomycetes. Some of them have a systemic action and can be used as foliar and soil fungicides.

The fungicidal compounds are of particular interest for controlling a large number of fungi in various crops or their seeds, especially wheat, rye, barley, oats, rice, Indian corn, lawns, cotton, soybeans, coffee, sugar cane, fruit and ornamentals in horticulture and viticulture, and in vegetables such as cucumbers, beans and cucurbits.

The novel compounds are particularly useful for controlling the following plant diseases:

Erysiphe graminis in cereals, Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits, Podosphaera leucotricha in apples, Uncinula necator in vines, Puccinia species in cereals. Rhizoctonia solani in cotton, Ustilago species in cereals and sugar cane, Venturia inaequalis (scab) in apples. Helminthosporium species in cereals, Septoria nodorum in wheat, Botrytis cinerea (gray mold) in strawberries and grapes, Cercospora arachidicoka in groundnuts, Pseudocercosporella herpotrichoides in wheat and barley, Pyricuiaria oryzae in rice, Phytophthora infestans in potatoes and tomatoes, Fusarium and verticillium species in various plants, Plasmopara viticola in grapes, Alternaria species in fruit and vegetables,

The compounds are applied by spraying or dusting the plants with the active ingredients, or treating the seeds of the plants with the active ingredients. They may be applied before or after infection of the plants or seeds by the fungi. Either the fungi themselves, or the plants, seeds, materials or the soil to be protected against fungus attack are treated with a fungicidally effective amount of the active ingredient.

The novel substances can be converted into conventional formulations such as solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application forms depend entirety on the purposes for which they are intended; they should at all events ensure a fine and uniform distribution of the active ingredient.

USE EAMPLES 1

Action on Plasmopara viticola

Leaves of potted vines of the Muller-Thurgau variety were sprayed with aqueous suspensions containing (dry basis) 80% of active ingredient and 20% of emulsifier. To assess the duration of action, the plants were set up, after the sprayed-on layer had dried, for 8 days in the greenhouse. Then the leaves were infected with a zoospore suspension of Plasmopara viticola. The plants were first placed for 48 hours in a water vapor-saturated chamber at 24.degree. C. and then in a greenhouse for 5 days at from 20.degree. to 30.degree. C. To accelerate and intensify the sporangiophore discharge, the plants were then again placed in the moist chamber for 16 hours. The extent of fungus attack was then assessed on the undersides of the leaves.

The results show that active ingredients 5, 15, 39, 40, 50, 59, 61, 62 and 67, applied as 0.025 wt% spray liquors, have a better fungicidal action (100%) than prior art comparatlve agents A and C (75%).

USE EXAMPLES 2

Action on Botrytis cinerea in paprika

Paprika seedlings of the "Neusiedler ldeal Elite" variety were sprayed, after 4 to 5 leaves were well developed, to runoff witn aqueous suspensions containing dry basis 80% of active ingredient and 20% of emulsifier. After the sprayed-on layer had dried, the plants were sprinkled with a conidial suspension of the fungus Botrytis cinerea, and placed at 22.degree. to 24.degree. C. in a chamber of high humidity. After 5 days, the disease had spread to such a great extent on the untreated plants that the necroses covered the major portion of the leaves.

The results show that active ingredients 5, 15, 59, 61, 62 and 67, applied as 0.05% spray liquors, have a better fungicidal action (90%) than prior art active ingredients B, C and D (60%).
