Abstract
Highly stereoselective syntheses (e.e. > 98%) of beta-aminoesters and beta-lactams were accomplished using enantiomerically pure tricarbonyl (eta(6)benzaldimine)chromium complexes in a Reformatsky type reaction promoted by ultrasound. A correlation between the configuration of co mplexed imines and absolute configuration of beta-lactam derivatives i s reported.
