SYNTHETIC STUDIES ON OPTICALLY ACTIVE β-LACTAMS. ASYMMETRIC SYNTHESIS OF β-LACTAMS BY THE CYCLOCONDENSATION UTILIZING CHIRAL HETEROCYCLIC COMPOUNDS DERIVED FROM L-(+)-TARTARIC ACID AND (S)-GLUTAMIC ACID

Asymmetric cyclocondensation of the chiral heterocyclic compounds (2,4) with imines (5) gave either cis- or trans-β-lactams with high diastereomeric purity up to 96percent, and the optically pure phenylalanine derivative (9) was obtained from the β-lactams produced.
