diastereoselective synthesis of cis-β-lactams via [2+2] cycloaddition reactions of sugar-imine derivative possessing free hydroxyl groups at C-2 and C-3 positions and ketenes is described. exo-Approach of sugar-imine with ketene leads to the stereoselective formation of cis product and it is facilitated by hydrogen bonding interaction of C2–OH with carbonylgroup of ketene. Docking studies show that these derivatives
