Sulfur-directed regioselective radical cyclization leading to β-lactams: Formal synthesis of (±)-PS-5 and (+)-thienamycin

A new method for the synthesis of β-lactams by tributyltin hydride (Bu3SnH)-mediated radical cyclizations of N-ethenyl-α-bromo amides bearing sulfur-substituent(s) at the terminus of the N-vinylic bond is described. N-[2-(Phenylthio)ethenyl]-α-
