Vanadium-catalyzed enantioselective oxidation of allyl sulfides

The enantioselective oxidation of allyl sulfides with a vanadyl complex of 3,5-diiodosalicylidene tert-leucinol as a catalyst and aqueous hydrogen peroxide as an oxidant afforded chiral allylsulfoxides with high enantioselectivities of up to 97.3% ee and moderate yields.
