Fungicidal alkoximinomethyldioxazine derivatives

Description

The invention relates to novel alkoximinomethyldioxazine derivatives, to a process 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 alkoximinomethyldioxazine derivatives of a constitution similar to those described below have fungicidal properties (compare, for example, WO-A 9504728). However, the fungicidal activity of these compounds, in particular at low application rates, leaves something to be desired. The novel alkoximinomethyldioxazine derivatives of the general formula (I) have now been found

in which

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

1

is attached is always linked to a carbon atom of the alkanediyl chain) or a grouping

in which

R

3

represents in each case optionally substituted alkyl or cycloalkyl,

R

1

represents hydrogen, cyano or in each case optionally substituted alkyl or cycloalkyl,

R

2

represents hydrogen or in each case optionally substituted alkyl or cycloalkyl,

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

and E

are identical or different and, independently of one another, each represents hydrogen, alkyl, halogenoalkyl or hydroxyalkyl, or

E

and E

or E

and E

or E

and E

together with the respective carbon atoms to which they are attached form a cycloaliphatic ring and

L

, L

, L

3

and L

, are identical or different and, independently of one another, each represents hydrogen, halogen, cyano, nitro, in each case optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl.

In the definitions, the saturated or unsaturated hydrocarbon chains, such as alkyl, alkanediyl, alkenyl or Alkinyl, are in each case straight-chain or branched, including in combination with heteroatoms, such as in alkoxy, alkylthio or alkylamino. If an alkyl or alkanediyl chain is interrupted by more than one heteroatom, these can be identical or different. If an alkyl or alkanediyl chain is interrupted by more than one oxygen atom, two oxygen atoms are not directly adjacent.

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 of naphthyl, in particular phenyl.

Heterocyclyl represents saturated or unsaturated, and also aromatic, cyclic compounds in which at least one ring member is a heteroatom, i.e. an atom different from carbon. If the ring contains a plurality of heteroatoms, these can be identical or different. Preferred heteroatoms are oxygen, nitrogen or sulphur. If appropriate, the cyclic compounds form a polycyclic ring system together with other carbocyclic or heterocyclic, fused-on or bridged rings. 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, if appropriate, form a polycyclic ring system with other carbocyclic, fused-on or bridged rings.

Furthermore, it has been found that the novel alkoximinomethyldioxazine derivatives of the general formula (I) are obtained when (process a) 3-(1-hydroxyphenyl-1-alkoximinomethyl)dioxazines of the general formula

in which

in which

G, R

1

, R

2

and Z are each as defined above, and

X represents halogen,

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 alkoximinomethyldioxazine derivatives of the general formula (I) have very strong fungicidal activity.

The compounds according to the invention may, if appropriate, be present as mixtures of different possible isomeric forms, in particular of stereoisomers, such as, for example, 20

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 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 Leptosphaeria species, for controlling diseases in viticulture and fruit and vegetable growing, such as, for example, against Venturia and Plasmopara species. or for controlling rice diseases, such as, for example, against Pyricularia species. Other cereal diseases, such as, for example, Septoria, Pyrenophora or Cochliobolus species, are controlled very successfully.

Furthermore, the compounds according to the invention may also be employed to increase the yield of crops. Moreover, they exhibit reduced toxicity and are tolerated well by plants.

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 employ, for example, organic solvents as auxiliary solvents. Essentially, the following are suitable for use as liquid solvents: 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 and 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 colorants 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%.

Depending on their particular physical and/or chemical properties, the active compounds can be converted into 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.

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

Process a)

0.69 g (0.003 mol) of 3-(3-trifluoromethyl-phenyl)-but-2-enoic acid, 0.39 g (0.0033 mol) of thionyl chloride and 10 ml of 1,2-dichloroethane are boiled under reflux for one hour. Volatile components are distilled off under reduced pressure and the residue, the crude 3-(3-trifluoromethyl-phenyl)-but-2-enoyl chloride, is dissolved in 20 ml of dimethylformamide. This solution is added dropwise to a mixture of 0.62 g (0.0027 mol) of (5,6-dihydro-[1,4,2]dioxazin-3-yl)-(2-hydroxy-phenyl)-methanone O-methyl-oxime and 0.848 g (0.0028 mol) of an 80% strength sodium hydride suspension in 30 ml of dimethylformamide, and stirring is continued for another 16 hours. The reaction mixture is then poured into 50 ml of water and extracted twice with 50 ml of ethyl acetate each time, the organic phase is dried over sodium sulphate and the solvent is distilled off under reduced pressure. The residue is chromatographed over silica gel using ethyl acetate/cyclohexane (1:1). This gives 0.99 g (82% of theory) of 2-[(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methoxyiminomethyl]-phenyl 3-(3-trifluoromethylphenyl)-but-2-enoate.

Preparation of the Starting Material

34 g (0.139 mol) of methyl 3-(3-trifluoromethyl-phenyl)-but-2-enoate are dissolved in 200 ml of methanol, admixed with 24.8 g (0.28 mol) of 45% strength aqueous sodium hydroxide solution and stirred at 20° C. for 16 hours. The solvent is distilled off under reduced pressure and the residue is taken up in 100 ml of water, acidified using approximately 150 ml of 2N hydrochloric acid (pH≈1) and extracted twice with 50 ml of ethyl acetate each time. The organic phase is dried over sodium sulphate, the solvent is distilled off under reduced pressure and the residue is stirred with petroleum ether. This gives 17 g (53% of theory) of 3-(3-trifluoromethyl-phenyl)-but-2-enoic acid.

Preparation of the Precursor

At 0° C., 33.2 g (0.183 mol) of dimethyl methoxycarbonylmethanephosphonate are added dropwise to a solution of 20.5 g (0.183 mol) of potassium tert-butoxide in 200 ml of tetrahydrofuran. At 20° C., 31.2 g (0.166 mol) of 3-(trifluoromethyl)-acetophenone are added dropwise, and the mixture is subsequently boiled under reflux for three hours. The solvent is distilled off under reduced pressure, and the residues are mixed with 200 ml of water and extracted twice with 100 ml of ethyl acetate each time. The organic phase is dried over sodium sulphate and the solvent is distilled off under reduced pressure. The product is then distilled at 0.5 torr and 80-90° C. This gives 34.6 g (85.4% of theory) of methyl 3-(3-trifluoromethyl-phenyl)-but-2-enoate as a mixture of stereoisomers.

EXAMPLE 2

Process a)

180 mg (0.0045 mol) of a 60% strength sodium hydride suspension are added to a solution of 1.08 g (0.0046 mol) of (5,6-dihydro-[1,4,2]dioxazin-3-yl)-(2-hydroxy-phenyl)-methanone O-methyl-oxime in 5 ml of dimethylformamide, and the mixture is stirred until evolution of gas ceases. At 0° C., 0.8 g (0.0045 mol) of 4-methoxyimino-3-methyl-pent-2-enoic chloride is added dropwise. The reaction mixture is allowed to stand for 10 minutes and poured into water, and the mixture is extracted with 10 ml of ethyl acetate. The organic phase is dried over sodium sulphate and the volatile components are distilled off under reduced pressure. The residue is stirred with petroleum ether. This gives 2.09 g (32.6% of theory) of 2-[(5,6-dihydro-[1,4,2]dioxazin-3-yl)-methoxyiminomethyl]-phenyl ester 4-methoxyimino-3-methylpent-2-enoate as oil.
