Abstract: Benzhydryl 2 beta-[(1,2,3-triazol-1-yl)methyl]-2 alpha-methylpenam- 3 alpha-carboxylate 1,1-dioxide was prepared by heating benzhydryl 2 beta-(azidomethyl)-2 alpha-methylpenam-3 alpha-carboxylate 1,1-dioxide with (trimethylsilyl)acetylene. The ester group was removed by hydrogenolysis to give sodium 2 beta-[(1,2,3-triazol-1-yl)methyl]-2 alpha-methylpenam-3 alpha-carboxylate 1,1-dioxide (3i, YTR-830), which was found to be a potent inhibitor of various bacterial beta-lactamases. A series of related compounds was prepared in a similar way, and all of these compounds show excellent beta-lactamase inhibitory properties.
