A diastereoselective synthesis of (±) c/s-β-1actams (5 and 6) via cycloaddition reactions of N1-(α-thiophenyl)benzyl imines (3) with acid chlorides (4) in the presence of triethylamine is described. The deprotection of N1-(α-thiophenyl)benzyl group has been achieved by oxidation using potassium persulfate to give N-unsubstituted β-lactams (7) in good yields.
