ABSTRACT
The synthesis and separation of the isomers of the pesticide cycloprothrin have been realized for the first time. Complete separation was achieved on a DAICEL CHIRALCEL OJ-H column (25 x 0.46 cm) for (1R, alpha*)-cycloprothrin isomers and on a DAICEL CHIRALCEL OD-H column (25 x 0.46 cm()) for (1S, alpha*)-cycloprothrin isomers. The insecticidal activity of (1R, alphaR)-cycloprothrin for the larvae of Mythimaseparata and Aphismedicagini was found to be about six times and four times higher, respectively, than that of racemic cycloprothrin.
