Abstract

<jats:title>Abstract</jats:title> <jats:p>The desymmetrization of meso-epoxides with thiols proceeded smoothly in dichloromethane or dichloroethane in the presence of a catalytic amount of a chiral scandium complex consisting of Sc(OTf)3 and chiral bipyridine 1, to afford the corresponding sulfides in high yields with high enantioselectivities.</jats:p>
