Chiral scandium-catalyzed highly stereoselective ring-opening of meso-epoxides with thiols
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.
