Asymmetric Syntheses of β-Lactams and Determination of Their Absolute Configuration

Reactions of chiral imines derived from D-glyceraldehyde and threonine derivatives with Oxglycylchloride gave optically active cis-substituted β-lactams.The absolute configuration of key intermediates were determined by X-ray analysis and chemical degradation. - Key words: Asymmetric syntheses, D-glyceraldehyde, threonine, β-lactam, Staudinger reaction
