METHOD FOR THE SYNTHESIS OF OPTICALLY ACTIVE ESTER OF CYCLOPROPANE CARBOXYLIC ACID AND ALLETROLONE WITH S-CONFIGURATION

An optically active (R)- or (S)-allethrolone X-sulphonate is reacted with a salt of 2,2-dimethyl-3-(2'-R1-2'-R2-vinyl)cyclopropanecarboxylic acid, in an organic solvent. X above represents a C1-C3 alkyl or a phenyl optionally substituted at the para position by a methyl or a fluorine, chlo...

Zusammenfassung:	An optically active (R)- or (S)-allethrolone X-sulphonate is reacted with a salt of 2,2-dimethyl-3-(2'-R1-2'-R2-vinyl)cyclopropanecarboxylic acid, in an organic solvent. X above represents a C1-C3 alkyl or a phenyl optionally substituted at the para position by a methyl or a fluorine, chlorine or bromine atom and R1 and R2 are defined in Claim 1. Esters of formula: are obtained in which the allethrolone has the antipode configuration, (S) or (R), of that of the sulfonate used. The process makes it possible to reuse (R)-allethrolone produced by resolution of racemic allethrolone. The esters (I) have an insecticidal action; they can be used, especially, in the form of an insecticidal composition.
