SYNTHETIC STUDIES ON CARBAPENEM ANTIBIOTICS FROM PENICILLINS. III. STEREOSELECTIVE RADICAL REDUCTION OF A CHIRAL 3-ISOCYANOAZETIDINONE: A TOTAL SYNTHESIS OF OPTICALLY ACTIVE CARPETIMYCINS

A new, efficient synthesis of the optically active carpetimycins 1 from penicillins has been achieved via, as key steps, aldol reaction of isonitrile 19, followed by n-Bu3SnH reduction.

4-Substituted-2-oxoazetidine compounds

The present invention relates to novel 4-substituted-2-oxoazetidine compounds and to processes for preparing the same. These compounds are useful intermediates for preparing antibiotics having the basic skeleton of Thienamycin.
