摘要

The asymmetric synthesis of (S)-2-sec-butyl-4,5-dihydrothiazole, one of the pheromone components of the male mouse, Mus musculus, has been achieved by induction of chirality through stereoselective alkylation reaction using non-cross-linked polystyrene (NCPS) supported 2-phenylimino-2-oxazolidine as a chiral auxiliary. This method is efficient, and the chiral auxiliary can be recovered by simple filtration. The final product was obtained in 91% ee and 23% overall yield.
