Asymmetric synthesis of monocyclic β-lactams from l-cysteine using photochemistry
摘要:
An asymmetric method to synthesize cis-configured beta-lactams using photochemistry has been developed. Aerobic photo-oxidation of L-cysteine-derived thiazolidine hydroxamate esters afforded C-3 hydroxylated products which when cyclized and deprotected gave the corresponding N-protio monocyclic beta-lactams.
