Selective Oxidation of Glycosyl Sulfides to Sulfoxides with Sodium Hypochlorite and Catalyzed by Metalloporphyrins
摘要:
An efficient and selective method for oxidation of glycosyl sulfides to the corresponding glycosyl sulfoxides with metalloporphyrins as catalysts and sodium hypochlorite as oxidant was achieved under mild conditions. High chemoselectivity and diastereomeric excesses were obtained. Both acid-labile protected groups and carbon-carbon double bonds of allyl groups tolerated under these conditions.
