A GENERAL APPROACH TO TRANS-CARBAPENEM ANTIBIOTICS. ENANTIOSELECTIVE SYNTHESIS OF KEY INTERMEDIATES FOR (+)-PS-5, (+)-PS-6, AND (+)-THIENAMYCIN

(S)-4--2-azetidinone prepared by chemico-enzymatic approach has been efficiently converted to key intermediates for the synthesis of natural trans-carbapenem antibiotics, (+)-PS-5, (+)-PS-6, and (+)-thienamycin.
