A New Stereoselective Route to Preparing Optically Active 2-Imino-penam Derivatives

A novel and simple procedure for preparation of (5R,6S)-2-benzylimino-6-bromo-3-isopropylidene-penam 2 and (5R,6S)-2-benzylimino-3-isopropylidene-penam 8 is described. The 2-imino-penam derivatives are prepared by modification of the Cooper reductive rear
