Article abstract of DOI:10.1246/cl.1990.1867

Direct conversion of 1-(3-chloro-2-hydroxy-1-p-methoxybenzyloxycarbonyl-1-propenyl)-4-(phenylsulfonylthio)azetidinones derived from penicillin G into 3-hydroxycephems was performed successfully by the action with BiCl3/Sn or TiCl4/Sn bimetal redox couples in DMF containing pyridine.
