Diastereoselective Synthesis of Enantiopure Acyclic β,β′-Disubstituted Vinylsulfoxides

Thermal elimination of sulfenic acid from enantiopure beta,beta'-disubstituted bis-sulfoxides allows the stereoselective synthesis of enantiopure acyclic beta,beta'-disubstituted vinylsulfoxides. This mild and stereospecific synthesis provides either ( E) or ( Z) vinylsulfoxides in high yields and is compatible with acid or base sensitive functional groups.
