Abstract

Un procédé de préparation d'un composé dont la formule générale où R1 représente un atome d'hydrogène ou un groupe alcoyle ou cycloalcoyle éventuellement substitué, R2 représente un groupe alcoyle ou cycloalcoyle éventuellement subsitué, chacun de R3 et R4 représente indépendamment un groupe alcoyle ou cycloalcoyle éventuellement substitué et chacun de R5 et R6 représente indépendamment un groupe alcoyle,cycloalcoyle, alcényle,alcynyle, aryle ou aralcoyle éventuellement substitué, qui comprent la réaction d'une hydrazone appropriée avec un dicarboxylate approprié. Utilisé pour la préparation de pyridyl imidazolinones ayant une activité herbicide.A process for the preparation of a compound whose general formula where R1 represents a hydrogen atom or an optionally substituted alkyl or cycloalkyl group, R2 represents an optionally substituted alkyl or cycloalkyl group, each of R3 and R4 independently represents an alkyl group or optionally substituted cycloalkyl and each of R5 and R6 independently represents an alkyl, cycloalkyl, alkenyl, alkynyl, aryl or optionally substituted aralkyl group, which comprise the reaction of an appropriate hydrazone with a suitable dicarboxylate. Used for the preparation of pyridyl imidazolinones with herbicidal activity.
