Oxime derivatives and their use as fungicides

Description

This application is a 371 of PCT/EP97/05475, which was filed on Oct. 6, 1997.

The invention relates to novel oxime derivatives, to a plurality of processes for their preparation and to their use as fungicides, and also to novel intermediates and to a plurality of processes for their preparation.

It is already known that certain oxime derivatives which are constitutionally similar to those described below have fungicidal properties (cf., for example, WO-A 9504728). However, in many instances the fungicidal activity of these compounds is unsatisfactory.

This invention, accordingly, provides the novel oxime derivatives of the general formula (I)

in which

A represents alkanediyl

Ar represents in each case optionally substituted arylene or heteroarylene,

G represents a single bond, alkanediyl which is optionally interrupted by hetero atoms (but where the carbon atom to which R

1

is attached is in each case linked with a carbon atom of the alkanediyl chain) or a grouping

in which

R

3

represents alkyl,

R

1

represents hydrogen, cyano or in each case optionally substituted alkyl, alkoxy, alkylthio, alkylamino, dialkylamino or cycloalkyl,

R

2

represents hydrogen or alkyl,

Y represents oxygen, sulphur or —NH— and

Z represents in each case optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, aryl or heterocyclyl.

In the definitions, the saturated or unsaturated hydrocarbon chains, such as alkyl, alkanediyl, alkenyl or alkinyl, are in each case straight-chain or branched, also attached to hetero atoms, such as in alkoxy, alkylthio or alkylamino. If an alkyl or alkanediyl chain is interrupted by more than one hetero atom, these are identical or different. If an alkyl or alkanediyl chain is interrupted by more than one oxygen atom, these are not adjacent to one another.

Halogen generally represents fluorine, chlorine, bromine or iodine, and also pseudohalogens, such as, for example, cyano, preferably fluorine, chlorine, bromine or cyano, in particular fluorine or chlorine.

Aryl represents aromatic mono or polycyclic hydrocarbon rings, such as, for example, phenyl, naphthyl, anthranyl, phenanthryl, preferably phenyl or naphthyl, in particular phenyl.

Heterocyclyl represents saturated or unsaturated, and also aromatic, cyclic compounds in which at least one ring member is a hetero atom, i.e. an atom which differs from carbon. If the ring contains a plurality of hetero atoms, these may be identical or different. Preferred hetero atoms are oxygen, nitrogen or sulphur. If appropriate, the cyclic compounds form, together with other carbocyclic or heterocyclic, fused-on or bridged rings, a polycyclic ring system. Preference is given to mono- or bicyclic ring systems, in particular to mono- or bicyclic aromatic ring systems.

Cycloalkyl represents saturated carbocyclic cyclic compounds which optionally form a polycyclic ring system with other carbocyclic fused-on or bridged rings.

Furthermore, it has been found that the novel oxime derivatives of the general formula (I) are obtained when (process a)) oximes of the general formula (II)

in which

A, Ar, Y and R

2

are as defined above,

are reacted with an alkylating agent of the general formula (III)

in which

G, R

1

and Z are as defined above and

X represents halogen, alkylsulphonyloxy or optionally substituted arylsulphonyloxy,

if appropriate in the presence of a diluent and if appropriate in the presence of an acid acceptor.

Finally, it has been found that the novel oxime derivatives of the general formula (I) have a very strong fungicidal activity.

If appropriate, the compounds according to the invention can be present as mixtures of various possible isomeric forms, in particular of stereoisomers, such as, for example, E and Z, or optical isomers. What is claimed are both the E and the Z isomers, the individual enantiomers, the racemates and also any mixtures of these isomers.

The halogenoketones of the formula (VIII) required as starting materials for carrying out the process e) according to the invention are generally known chemicals for synthesis.

Suitable diluents for carrying out the process a) according to the invention are all inert organic solvents. These preferably include aliphatic, alicyclic or aromatic hydrocarbons, such as, for example, petroleum ether, hexane, heptane, cyclohexane, methylcyclohexane, benzene, toluene, xylene or decalin; halogenated hydrocarbons, such as, for example, chlorobenzene, dichlorobenzene, dichloromethane, chloroform, carbon tetrachloride, dichloroethane or trichloroethane; ethers, such as diethyl ether, diisopropyl ether, methyl t-butyl ether, methyl t-amyl ether, dioxane, tetrahydrofuran, 1,2-dimethoxyethane, 1,2-diethoxyethane or anisole; ketones, such as acetone, butanone, methyl isobutyl ketone or cyclohexanone; nitriles, such as acetonitrile, propionitrile, n- or i-butyronitrile or benzonitrile; amides, such as N,N-dimethylformamide, N,N-dimethylacetarnide, N-methylformanilide, N-methylpyrrolidone or hexamethylphosphoric triamide; esters such as methyl acetate or ethyl acetate; sulphoxides, such as dimethyl sulphoxide, or sulphones, such as sulpholane.

If appropriate, process a) according to the invention is carried out in the presence of a suitable acid acceptor. Suitable acid acceptors are all customary inorganic or organic bases. These preferably include alkaline earth metal or alkali metal hydrides, hydroxides, amides, alkoxides, acetates, carbonates or bicarbonates, such as, for example, sodium hydride, sodium amide, sodium methoxide, sodium ethoxide, potassium tert-butoxide, sodium hydroxide, potassium hydroxide, ammonium hydroxide, sodium acetate, potassium acetate, calcium acetate, ammonium acetate, sodium carbonate, potassium carbonate, potassium bicarbonate, sodium bicarbonate or ammonium carbonate, and also tertiary amines, such as trimethylamine, triethylamine, tributylamine, N,N-dimethylaniline, N,N-dimethylbenzylamine, pyridine, N-methylpiperidine, N-methylmorpholine, N,N-dimethylaminopyridine, diazabicyclooctane (DABCO), diazabicyclononene (DBN) or diazabicycloundecene (DBU).

The fact that the active compounds are well tolerated by plants at the concentrations required for controlling plant diseases permits the treatment of aerial parts of plants, of propagation stock and seeds, and of the soil.

The active compounds according to the invention can be employed particularly successfully for controlling cereal diseases, such as, for example, against Erysiphe species, for controlling diseases in viticulture and fruit and vegetable growing, such as, for example, against Venturia, Sphaerotheca, Podosphaera, Phytophthora and Plasmopara species, or for controlling rice diseases, such as, for example, against Pyricularia species. Cereal diseases, such as, for example, Septoria, Pyrenophora or Cochliobolus species, are also successfully controlled. Furthermore, the compounds according to the invention may also be employed to increase the yield of crops.

Depending on their particular physical and/or chemical properties, the active compounds can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and microencapsulations in polymeric substances and in coating compositions for seeds, and ULV cool and warm fogging formulations.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam formers. If the extender used is water, it is also possible to use organic solvents as auxiliary solvents, for example. Suitable liquid solvents are essentially aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, alcohols such as butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide or dimethyl sulphoxide, or else water. Liquefied gaseous extenders or carriers are to be understood as meaning liquids which are gaseous at standard temperature and under atmospheric pressure, for example aerosol propellants such as halogenated hydrocarbons, or else butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as highly disperse silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else 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, or else protein hydrolysates. Suitable dispersants are: for example lignin-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else 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 colourants such as inorganic pigments, for example iron oxide, titanium oxide and 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%.

The active compounds according to the invention can be used as such or in their formulations also mixed with known fungicides, bactericides, acaricides, nematicides or insecticides in order thus, for example, to widen the spectrum of action or to prevent development of resistance. In many cases, synergistic effects are achieved, i.e. the activity of the mixture exceeds the activity of the individual components.

PREPARATION EXAMPLES

Example 1

A solution of 0.5 g (1.9 mmol) of 2-[(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methoxy-imino-methyl]-benzaldehyde oxime in 10 ml of dimethylformamide is cooled to 0° C. and, under argon, admixed with 0.063 g (2.1 mmol) of an 80% strength suspension of sodium hydride. A solution of 0.42 g (2.1 mmol) of 1-(1-chloroethyl)-4-cyclohexylbenzene in 2 ml of dimethylformamide is added dropwise to this mixture, which is stirred without any further cooling for 4 hours. The reaction mixture is poured into 150 ml of water and extracted 3 times with 100 ml of ethyl acetate each time. The combined organic phases are dried over magnesium sulphate and concentrated under reduced pressure. The residue is chromatographed over silica gel using cyclohexane/ethyl acetate (3:1). This gives 0.6 g (70% of theory) of 2-[(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methoxyirninomethyl]-benzaldehyde O-[1-(4-cyclo-hexylphenyl)-ethyl] oxime.

The mixture is poured into 500 ml of water and extracted three times with 100 ml of dichloromethane each time. The combined organic phases are dried over magnesium sulphate and concentrated under reduced pressure. The residue is chromatographed over silica gel using cyclohexane/ethyl acetate (4:1). This gives 2.4 g (57% of theory) of 2-[(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methoxyimino-methyl]-benzaldehyde oxime.

Preparation of the Precursor

Example IV-1

19.5 g (0.14 mol) of N-methylmorpholine N-oxide are added to a solution of 15 g (0.056 mol) of (2-chloromethylphenyl)-(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methanone O-methyl oxime in 150 ml of dimethylformamide, and the mixture is stirred at 120° C. for 2 hours. After cooling, the mixture is poured into 1000 ml of water and extracted three times with 200 ml of ethyl acetate each time. The combined organic phases are dried over magnesium sulphate and concentrated under reduced pressure. The residue is stirred with diisopropyl ether and the resulting solid is filtered off with suction. This gives 10.5 g (76% of theory) of 2-[(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methoxyimino-methyl]-benzaldehyde.

in 500 ml of dichloromethane is added dropwise to this mixture, at which the reaction mixture warms to 30° C., and stirring is continued for a further 3 hours. The reaction mixture is poured onto 21 of ice-water and extracted 3 times with 300 ml of dichloromethane each time. The combined organic phases are dried over magnesium sulphate and concentrated under reduced pressure. The residue is stirred with diiisopropyl ether and the resulting solid is filtered off with suction (59.1 g). The filtrate is concentrated under reduced pressure and the residue is chromatographed over silica gel using cyclohexane/ethyl acetate (3:1). This gives a further 4 g of product. Altogether, 63.1 g (76% of theory) of (2-chloromethyl-phenyl)-(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methanone O-methyl oxime are obtained.

A solution of 0.4 g (1.52 mmol) of 2-[(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methoxy-imino-methyl]-benzaldehyde oxime in 10 ml of dimethylformamide is cooled to 0° C. and, under argon, admixed with 0.055 g (1.82 mmol) of an 80% strength suspension of sodium hydride. A solution of 0.37 g (1.52 mmol) of 2-bromo-1-(p-tolyl)-propan-1-one O-methyl oxime in 2 mnl of dimethylformamide is added dropwise to this mixture, which is stirred without any further cooling for 4 hours. The reaction mixture is poured into 100 ml of water and extracted 3 times with 100 ml of ethyl acetate each time. The combined organic phases are dried over magnesium sulphate and concentrated under reduced pressure. The residue is chromatographed over silica gel using cyclohexane/ethyl acetate (3:1). This gives 0.42 g (63% of theory) of 2-[(5,6-dihydro-[1 ,4,2]dioxazin-3-yl)-methoxyimino-methyl]-benzaldehyde O-[2-methoxyimino-1 -methyl-2-(p-tolyl)-ethyl] oxime.

Preparation of the Starting Material

Example (III-a-1)

2.27 (10 mmol) of 2-bromo-1-(p-tolyl)-propan-1-one are dissolved in 10 ml of acetic acid and, at 20° C., admixed with 1.25 g (15 mmol) of hydroxylammonium chloride and 2.07 g (15 mmol) of sodium acetate. After 14 hours, the solvent is distilled off under reduced pressure, the residue is taken up in 100 ml of ethyl acetate and the organic phase is separated off, dried over 50 g of magnesium sulphate and concentrated. This gives 2.5 g (99% of theory) of 2-bromo-1-(p-tolyl)-propan-1-one O-methyl oxime as a mixture of isomers (e/z 70/30).
