Patent

CA 2301172

The invention relates to a method for producing compounds of formula (I), wherein R1 is hydrogen or C1-C4 alkyl, R2 is hydrogen, C1-C6alkyl, C3-C6 cycloalkyl or a radical -CH2B, A is an unsubstituted or substituted, aromatic or non-aromatic, monocyclic or bicyclic heterocyclic radical and B is phenyl, 3-pyridyl or thiazolyl, these being substituted. The inventive method is characterised in that a compound of formula (II) wherein R1, R2 and A have the same meanings as in formula (I) and R3 is unsubstituted or substituted C11-C22 alkyl, C7-C16 cycloalkyl, C3-C20 alkenyl, C3-C20 alkinyl, N(R4)R5, optionally substituted aryl with the exception of unsubstituted and substituted phenyl, or an optionally substituted heterocyclic radical, R4 is hydrogen or C1-C12 alkyl and R5 is hydrogen, C1-C12 alkyl, C1-C12 alkyl carbonyl or C1-C12 alkoxy carbonyl is hydrolysed. The invention also relates to a method for producing compounds of formulae (II) and (III), and to a method for combating pests using compounds of formula (II). The compounds of formula (I) are suitable for producing pesticide mixtures.

L'invention concerne un procédé de production de composés de la formule (I) où R¿1? représente de l'hydrogène ou alkyle C¿1?-C¿4?; R¿2? représente de l'hydrogène, alkyle C¿1?-C¿6?, cycloalkyle C¿3?-C¿6? ou un groupe -CH¿2?B; A représente un groupe monocyclique, bicyclique ou hétérocyclique, aromatique ou non aromatique, substitué ou non subsitué; et B représente phényle, 3-pyridyle ou thiazolyle qui sont substitués; L'invention est caractérisée en ce que l'on hydrolyse un composé de la formule (II) où R¿1?, R¿2? et A ont la même signification que dans la formule (I) et R¿3? représente alkyle C¿11?-C¿22?, cycloalkyle C¿7?-C¿16?, alcényle C¿3?-C¿20?, alkinyle C¿3?-C¿20?, N(R¿4?)R¿5?, substitués ou non substitués, ou un groupe hétérocyclique éventuellement subsituté; R4 représente de l'hydrogène ou alkyle C¿1?-C¿12?; R¿5? représente de l'hydrogène, alkyle C¿1?-C¿12?, alkyle-carbonyle C¿1?-C¿12? ou alcoxy-carbonyle C¿1?-C¿12?. L'invention concerne également un procédé de production de composés des formules (II) et (III), ainsi qu'un procédé permettant de lutter contre les parasites avec la formule (II). Les composés de la formule (I) conviennent à la production de mélanges pesticides.
