Alkyl or alkyl moiety of an alkoxy group means, depending on the number of carbon atoms in each case, the following groups: methyl, ethyl, n-propyl, isopropyl, n-, iso-, sec- or tert. butyl and pentyl and hexyl isomers. Alkenyl residues which may be mentioned are, in particular, vinyl, allyl, methallyl, butenyl, methylbutenyl and their isomers, while cycloalkyl radicals are cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl. Halogen means fluorine, chlorine, bromine or iodine.

German application 2,212,268 states in general terms that N-haloacylated anilinoalkanecarboxylic acid esters have a selective herbicidal action. However, only a few N-haloacetylated 2,6-di-alkyl-anilinoacetic acids and their esters have been named and found to have herbicidal activity. It does not mention any microbicidal, in particular phytosanitary, effect.

It has now surprisingly been found that compounds with a clearly different structure of the formula I have a very advantageous spectrum of plant fungicides for the protection of useful plants for practical purposes. Within the scope of this invention, useful crops include, for example, cereals, corn, rice, vegetables, sugar beet, soybeans, peanuts, fruit trees, ornamentals, but above all vines, hops, cucumbers (cucumber, pumpkin, melons), moths, solanacee and as well as banana, cocoa and natural rubber crops.

The active compounds of the formula I can be used to prevent or eradicate fungi present in plants or parts of plants (fruits, flowers, foliage, stems, tubers, roots) of such and closely related useful crops, so that subsequently growing plant parts are also protected against such fungi. The active ingredients are effective against phytopathogenic fungi belonging to the following classes: Ascomycetes (e.g. Erysiphaceae); Basidiomycetes, such as 3,61478 primarily rust fungi; Fungi imperfecti (e.g. Moniliales); above all, however, in particular, the Phycomycetes class includes Oomycetes such as Phytophtora, Peronaspora, Pseudoperonospora, Pythium or Plasmopara. In addition, the compounds of the formula I have a systemic effect. They can also be used as pickling agents to treat seeds (fruits, tubers, grains) and plant cuttings to protect them against fungal infections and against phytopathogenic fungi present in the soil.

Preferred microbicides are compounds of the formula I in which methyl represents, R 2 is in the ortho position to the amino group and represents methyl, ethyl or chlorine, and R 9, R 6, R 8 and R 8 have the same meaning as above. These are called compound group Ia.

Of these compounds of formula Ia, mention may be made, by virtue of their activity, of compounds in which R1 represents an alkyl, alkenyl or cycloalkyl radical having 2 to U carbon atoms and R8 and R8 have the same meaning as above, the substituents R1, R25 of the phenyl ring being The total number of C atoms in Rg and Rg does not exceed 4.

Another important subgroup are those compounds of formula I in which R 2 represents hydrogen, C 1 -C 6 alkyl or halogen and the substituents R 9 and R 8 are hydrogen, while the substituents R 1, R 8 and R 4 have the same meaning as in formula I.

For certain uses, e.g. as pickling agents or against fungi, preference is given to compounds of the formula I or of subgroup Ia in which R1 represents a cyanomethyl or Roda nomine group.

The compounds of formula I are prepared, for example, by acylation of a compound

Ri I? H3 ch - COOR3 λΦ / NH w 11 R6 r2 with a carboxylic acid of formula

ho-co-r4 III

or its acid halide, acid anhydride or ester, in individual cases also its acid amide (re-amidation).

According to another method, the compounds of formula I can also be prepared starting from acylanilides of the formula nh-co-r4 iv

Rr 6 R2 and convert them with butyllithium or sodium hydride to the corresponding alkali salt, which is then reacted with a compound of formula? H3 v

Hal-CH-C00R3 is obtained from the desired end product, or acylanilides of formula IV, by reacting them with a compound of formula V in the presence of an alkali carbonate (such as sodium carbonate or potassium carbonate) as a proton acceptor, preferably by adding catalytic amounts of alkali iodide (such as KJ).

In formulas II, III, IV and V, R 1 is as defined in formula I, while "Hai" means a halogen atom, preferably chlorine or bromine, or some other easily cleavable residue. The phrase "acid halide" preferably means acid chloride or acid bromide.

The reactions may be carried out in solvents or diluents which are inert to the reaction components, or without these substances.

D

Examples which may be mentioned are: Aliphatic or aromatic hydrocarbons, such as benzene, toluene, xylenes, petroleum ether; halogenated hydrocarbons such as chlorobenzene, methylene chloride, ethylene chloride, chloroform; ethers and ether-like compounds such as dialkyl ether, dioxane, tetrahydrofuran; nitriles such as acetonitrile; N, N-dialkylated amides such as dimethylformamide; anhydrous acetic acid, dimethyl sulfoxide, ketones such as methyl ethyl ketone, and mixtures of such solvents.

Reaction temperatures are 0-180 ° C, preferably 20-12 ° C. In many cases, it is preferable to use acid-binding agents or condensing agents. Suitable such are tertiary amines, such as trialkylamines (e.g. triethylamine), pyridine and pyridine bases, or inorganic bases, such as alkali and alkaline earth metal oxides and hydroxides, bicarbonates, and carbonates, and sodium acetate. In addition, an excess of the aniline derivative of the formula II used in each case can be used as the acid-binding agent.

The production process starting from the starting materials of the formula II can also be carried out without an acid-binding agent, in which case it is advantageous in some cases to pass nitrogen through the mixture to displace the hydrogen halide formed. In other cases, it is highly preferred to add dimethylformamide as a reaction catalyst.

The details for the preparation of intermediates of formula II correspond to the methods generally set out for the preparation of anilino-alkanoic acid esters in J. Or g. Chem. 30, 41 01 (1965),

Tetrahedron 1967, 487,

Tetrahedron, 1967, 493,

The compounds of formula I have an asymmetric carbon atom and can be cleaved into optical antipodes in a conventional manner. In this case, the enantiomeric D-form has a stronger microbicidal effect.

In the context of the invention, those compounds having the D-configuration of the formula I are preferred. These D-forms generally have a negative rotation angle when measured in ethanol or acetone.

‘V t ** 6 61478

To prepare pure optical D-antipodes, for example, a racemic compound of formula R1 is prepared

Rsv ^) \ l * 3

KMJ / -NH-CH-COOH VI

R6 r2 where R- | , R 2) R c, and R 8 are as defined in formula I and this is then reacted in a manner known per se with an N-containing optically active base to give the corresponding salt. Fractional crystallization of the salt followed by liberation of the acid of formula VI enriched with an optical D-antipode and optionally repeating (also multiplying) the salt formation, crystallization and liberation of the α-anilinopropionic acid of formula VI periodically gives pure Form D. From this, the optical D-configuration of the ester of formula II can then be prepared in a conventional manner, e.g. in the presence of HCl or H 2 SO 4, with methanol or ethanol, if desired.

Suitable optically active organic bases are, for example, α-phenylethylamine.

Instead of fractional crystallization, the enantiomeric Form D can be of the formula

R 1 R y-1 CH 3 - nh- + ch-coor 3 VI 1 r 6 i "7 R 2 is also prepared by diazotizing the amino group in naturally occurring N-alanine in the presence of e.g. HCl or HBr and thus replacing it with halogen while N 2 cleaves and the L-configuration remains unchanged, then optionally esterified with methanol or ethanol and then reacted with aniline of formula 7 61 4 7 8 J; v £) V-NH2 VI11 where there is essentially an inversion to formula VII For the D-configuration (J. Am. Chem. Soc. 7-6, 6056) Irrespective of the optical isomer mentioned, Atrop isomerism relative to the phenyl-N <axis is generally observed in cases where the phenyl ring is substituted at at least the 2,6-position and at the same time asymmetrically with respect to this axis (possibly also in the presence of additional substituents.) This is further due to the steric hindrance of the residues CKo -CH-COOR "C0_R4 attached to the N atom.

In addition, regardless of the above-mentioned optical isomerism, a cis-trans isomer relative to the double bond may be present in the case of alkenyl.

If no determined synthesis is carried out to isolate the pure isomers, the product is generally obtained as a mixture of two optical isomers, two atropisomers, two cis, trans isomers or a mixture of these possible isomers. However, the in principle more favorable fungicidal effect of the enantiomeric form D (compared to the D, L form or L form) remains unchanged and is not significantly affected by the Atrop isomer or the cis / trans isomer.

The following examples further illustrate the invention without, however, limiting it. Temperatures are given in degrees Celsius.

Unless otherwise stated, the active ingredient of the formula I, which may be present in optically active form, is in each case a racemic mixture.
