The treatment of sulfinyl chlorohydrins with KO-t-Bu in THF generates epoxy vinyl sulfoxides that undergo an efficient base-induced rearrangement to generate enantiopure hydroxy 2-sulfinyl dienes. This novel process takes place with high chemo- and stereoselectivity. The chirality at sulfur effectively controls the geometry of the trisubstituted alkene.
