摘要

6'-Acylaminopenicillanoyloxymethyl esters of penicillanic acid 1,1-dioxide are useful as antibacterial agents. The 6'-aminopenicillanoyloxymethyl ester, halomethyl esters, alkylsulfonyloxymethyl esters and arylsulfonyloxymethyl esters of penicillanic acid 1,1-dioxide are all useful intermediates for the aforesaid antibacterial agents.
