CONCERNING THE INTERMEDIACY OF MONOCYCLIC β-LACTAMS IN PENICILLIN BIOSYNTHESIS: SYNTHESIS AND ATTEMPTED BIOCONVERSION OF SECO-ISOPENICILLIN N

The title compound (3a) was synthesized as its dimer by the skeletal rearrangement of protected isopenicillin N-sulfoxide, hydrogenation, hydrolysis of the thiazoline ring, oxidative dimerization and deprotection.The reductive conversion of the dimer to m
