Highly 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 carbonyl group of ketene. Docking studies show that these derivatives are having greater affinity towards PBP and it has been validated by in vivo studies. Among the different sugar-based azetidine-2-ones, compounds 6a and 6d were superior in activity to the commercial antibiotic tetracycline.
