Glycosylation of racemic and optically active α-hydroxy β-lactams by reaction with a few glycal derivatives in the presence of catalytic amounts of iodine has provided stereospecific formation of α-glycosides. This method has been extended for the preparation of optically active hydroxy β-lactams in excellent yields. The stereochemistry and nature of the glycals as well as the stereochemistry of the
