Description
Fungicidal optically active 2-imidazolin-5-one and
2-imidazoline-5-thione derivatives
The subject of the present invention is new optically active 2-imidazolin-5-one and 2-imidazoline5-thione derivatives for use in plant protection, and their process of preparation.
It also relates to fungicidal compositions based on these compounds and to a process for the treatment of fungal diseases of crops using these compounds .
The racemic compounds derived from 2imidazolin-5-ones and 2-imidazoline-5-thiones are described in European Patent Applications EP 551048 and EP 599749, and in International Application WO 94/01410.
It has now been discovered that one of the optical isomers of these compounds has a biological activity which is much greater than that of the other isomer and that of the racemic modification.
One object of the invention is therefore to provide new compounds which are useful in controlling fungal diseases of crops.
Another object of the invention is to provide new 2-imidazolin-5-one and 2-imidazoline-5-thione derivatives which are active at a dose which is reduced with respect to that of the racemic derivatives.
It has now been found that these objects could be achieved by virtue of the products of the

Variant A;
First stage:
In a first stage of this variant, a description is given of the preparation of the optical isomers of formula I from α-amino acids which are optically pure or greatly enriched in one enantiomer. Optically active compound greatly enriched in a specific enantiomer is understood to mean a compound containing at least 80 %, preferably 95 %, of this enantiomer.
The optical isomers of formula I are prepared according to three series of processes, depending on the meaning of the (M)P-RJ group.

The reaction is carried out in a solvent and in the presence of a base. It is possible to use, as base, an alkoxide, for example potassium tert-butoxide, an alkali metal or alkaline earth-metal hydroxide, an alkali metal carbonate or a tertiary amine. It is possible to use, as solvent, ethers, cyclic ethers, alkyl esters, acetonitrile, alcohols containing 1 to 3 f carbon atoms or aromatic solvents, for example tetrahydrofuran, at a temperature between -5°C and +80eC.
A variant of the method described above consists in using the so-called one-pot process (Diagram 1) as described in European Patent Application EP 551048. This method consists in starting directly from the isothiocyanate of formula IV which is treated with a compound of formula V in a solvent and in the presence of a base as described above.

The invention also relates to the compositions for protecting plants against fungal diseases, comprising, in combination with one or more solid or liquid vehicles which are acceptable in agriculture and/or surface-active agents which are also acceptable in agriculture, one (or a number of) active material which is a compound of formula I.
In fact, for their practical use, the compounds according to the invention are rarely used on their own. Most often these compounds form part of compositions. These compositions, which can be used as fungicidal agents, contain, as active material, a compound according to the invention as described above as a mixture with solid or liquid vehicles which are acceptable in agriculture and surface-active agents which are also acceptable in agriculture. In particular, the customary inert vehicles and the customary surface-active agents can be used. These compositions also form part of the invention.
These compositions can also contain all kinds of other ingredients such as, for example, protective colloids, adhesives, thickening agents, thixotropic agents, penetration agents, stabilizing agents, sequestering agents and the like. More generally, the compounds used in the invention can be used in combination with any of the solid or liquid additives which correspond to the usual formulating techniques.
Generally, the compositions according to the
AP/P/ 9 4/ 0 0 6 48 bad original ft
AP ο 0 0 4 6 1 invention usually contain approximately 0.05 to 95 % (by weight) of a compound according to the invention (subsequently called active material), one or more solid or liquid vehicles and, optionally, one or more surface-active agents.
The term vehicle, in the present account, means a natural or synthetic, organic or inorganic material with which the compound is combined in order to facilitate its application to the plant, to seeds or to the soil. This vehicle is therefore generally inert and it has to be acceptable in agriculture, especially to the treated plant. The vehicle can be solid (clays, natural or synthetic silicates, silica, resins, waxes, solid fertilizers, and the like) or liquid (water, alcohols, especially butanol, and the like).
The surface-active agent can be an emulsifying, dispersing or wetting agent of ionic or nonionic type or a mixture of such surface-active agents. There may be cited, for example, salts of poly(acrylic acids), salts of lignosulphonic acids, salts of phenolsulphonic or naphthalenesulphonic acids, polycondensates of ethylene oxide with fatty alcohols or fatty acids or fatty amines, substituted phenols (especially alkylphenols or arylphenols), salts of esters of sulphosuccinic acids, derivatives of taurine (especially alkyltaurates), phosphoric esters of polycondensates of ethylene oxide with alcohols or phenols, esters of fatty acids and of polyols, and the

AP Ο Ο Ο 4 6 1 derivatives of the above compounds having sulphate, sulphonate or phosphate functional groups. The presence of at least one surface-active agent is generally indispensable where the compound and/or the inert vehicle are not soluble in water and where the vector agent of the application is water.
Thus, the compositions for agricultural use according to the invention can contain the active materials according to the invention within very wide limits, ranging from 0.05 % to 95 % (by weight). Their surface-active agent content is advantageously between O % and 40 % by weight. q
These compositions according to the invention C c
are themselves in fairly diverse, solid or liquid forms.
There may be mentioned, as solid composition forms, powders for dusting (containing the compound at a content of up to 100 %) and granules, especially those obtained by extrusion, by compacting, by 20 impregnation of a granulated vehicle, or by granulation from a powder (the content of the compound in these granules being between 0.5 and 80 % for the latter cases), tablets or effervescent tablets.
The compounds of formula (I) can also be used 25 in the form of powders for dusting; it is also possible to use a composition comprising 50 g of active material and 950 g of talc; it is also possible to use a composition comprising 20 g of active material, 10 g of

As composition forms which are liquid or 5 intended to constitute liquid compositions during application, there may be mentioned solutions, in particular water-soluble concentrates, emulsifiable concentrates, emulsions, suspension concentrates, aerosols, wettable powders (or sprayable powder), pastes or gels.
The emulsifiable or soluble concentrates most often comprise 10 to 80 % of active material, while the ready-to-apply solutions or emulsions contain 0.001 to 20 % of active material.
In addition to the solvent, the emulsifiable concentrates can contain, when this is necessary, 2 to 20 % of suitable additives such as the stabilizing agents, surface-active agents, penetration agents, corrosion inhibitors, dyes or adhesives mentioned above.
It is possible, by diluting these concentrates with water, to obtain emulsions of any desired concentration which are particularly suitable for application to crops.

The wettable powders (or sprayable powders) are generally prepared so that they contain 20 to 95 % of active material, and they generally contain, in addition to the solid vehicle, from 0 to 30 % of a wetting agent, from 3 to 20 % of a dispersing agent and, when necessary, from 0.1 to 10 % of one or more stabilizing agents and/or other additives, such as penetration agents, adhesives, or anticaking agents, dyes, and the like.

The compounds according to the invention can 5 be formulated in the form of water-dispersible granules also included in the scope of the invention.
These dispersible granules, with an apparent density generally between approximately 0.3 and 0.6, have a particle size generally between approximately
150 and 2,000 and preferably between 300 and 1,500 microns.
The active material content of these granules is generally between approximately 1 % and 90 %, and preferably between 25 % and 90 %.
The remainder of the granule is essentially composed of a solid filler and optionally of surface-active adjuvants which confer water( dispersibility properties on the granule. These ( granules can be essentially of two distinct types depending upon whether the filler used is soluble or insoluble in water. When the filler is water-soluble, it can be inorganic or, preferably, organic. Excellent results have been obtained with urea. In the case of an insoluble filler, the latter is preferably inorganic, such as, for example, kaolin or bentonite. It is then advantageously accompanied by surface-active agents (at an amount of 2 to 20 % by weight of the granule) of which more than half consists, for example, of at least

Moreover, although this is not indispensable, it is possible to add other adjuvants such as antifoaming agents.
The granule according to the invention can be prepared by mixing the required ingredients and then granulating according to several techniques known per se (pelletizer, fluid bed, atomizer, extrusion, and the like). Generally, the preparation is completed by crushing followed by sieving to the particle size chosen within the abovementioned limits. It is alternatively possible to use granules obtained as above and then impregnated with a composition ί containing the active material.
