A variety of 4-substituted ß-lactams can be readily prepared by the radical addition-transfer of 4-S-xanthyl-azetidinones to unactivated olefins. For this radical chain process to operate efficiently it is necessary to place an acyl group on the nitrogen of the azetidinone ring. © The Japan Institute of Heterocyclic Chemistry.
