REDUCTION OF β-HYDROXYSULFOXIDES: APPLICATION TO THE SYNTHESIS OF OPTICALLY ACTIVE EPOXIDES

Solladie, Guy,Demailly, Gilles,Greck, Christine

, p. 435 - 438 (2007/10/02)

β-hydroxysulfoxides of opposite stereochemistry can be prepared in very high diastereoisomeric excesses (90 to 95 percent) by reduction of β-ketosulfoxides with DIBAL or DIBAL/ZnCl2.A very efficient method to transform these reduction products into optically active epoxides is also described.
