Preliminary Experiments for Asymmetric Total Synthesis of the Thienamycin-Like γ-Lactam

Optically active bicycle γ-lactam carboxylates (3 and 4) were readily synthesized by employing chiral 5-alkylated pyrrolidin-2-one (9b) obtained from an asymmetric alkylation with tin(II) enolate (6a) onto 5-acetoxypyrrolidin-2-one (7b).
