title: Asymmetric synthesis of beta-lactams using chiral-memory effect on photochemical gamma-hydrogen abstraction by thiocarbonyl group.
abstract: Optically active beta-lactams were synthesized via photochemical intramolecular gamma-hydrogen abstraction reaction of thioimides involving a highly-controlled chiral-memory effect.
