Synthesis and beta-lactamase inhibitory properties of 2 beta-[(1,2,3-triazol-1-yl)methyl]-2 alpha-methylpenam-3 alpha-carboxylic acid 1,1-dioxide and related triazolyl derivatives.

R G Micetich et al.

Journal of medicinal chemistry, 30(8), 1469-1474 (1987-08-01)

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
