SYNTHETIC STUDIES ON CARBAPENEM ANTIBIOTICS FROM PENICILLINS. VI. SYNTHESES OF OPTICALLY ACTIVE O-METHYLCARPETIMYCIN AND O-METHYL-6-EPICARPETIMYCIN

The syntheses of the optically active O-methylcarpetimycin 2a and O-methyl-6-epicarpetimycin 2b were achieved by a route involving one-pot syntheses of 5a and 5b from 3.
