DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) The enantiomer pair 1R-trans-S- and 1S-trans-R-cypermethrin is obtained from a mixt. of cypermethrin enantiomers, as a very active synergistic insecticide, with low toxicity to warm-blooded species. Thus, a mixt. of trans-cypermethrin enantiomers was epimerized into the above enantiomer pair by heating at 60° with anhyd. Et3N, under N. The pure (99.5%) product was obtained by seeding crystn. and recrystn. from iso-PrOH. In lab. expts., the 1R-trans-S - 1S-trans-R enantiomer pair was more active against Acanthoscelides obtectus, Lucilia sericata and Tribolium confusum, than the 1R-cis-S - 1S-cis-R isomer pair. .

(ibid., 2006, 40, 721) is given, concerning an in vivo unidirectional chiral inversion of (+)-q-cypermethrin to (-)-q-cypermethrin. The employed anal. approach is discussed to lack proper chromatog. selectivity to allow postulation of in vivo unidirectional bioinversion of (+)-q-cypermethrin. .
