2-Oxo-1,3-dioxol-4-ylmethyl esters of penicillanic acid 1,1-dioxide
摘要:
Certain novel 2-oxo-1,3-dioxol-4-ylmethyl esters of penicillanic acid 1,1-dioxide (sulbactam) hydrolyze readily in vivo to liberate the corresponding free acid. The novel esters of this invention are useful therefore as antibacterial agents and beta-lactamase inhibitors.
