Chiral 3-substituted 5-hydroxypyrrolidin-2-one 12, useful for the synthesis of thienamycin-like γ-lactam, was successfully synthesised by utilising highly diastereoselective alkylation with the tin(II) enolate of 7 onto acetaldehyde, ammonolysis of the resultant amide 9, and oxidative cyclisation of 11.
