Abstract

1405793 Silyl esters of penicillanic and cephalosporanic acid derivatives E R SQUIBB & SONS Inc 3 Aug 1972 [14 Sept 1971 (4)] 36403/72 Heading C3S [Also in Division C2] Novel antibacterial trimethylsilyl esters of DL - 6 - [2 - (acetylthio) - 2 - phenylacetamido]. penicillanic acid and DL-6-[2-[(ethylthio and butylthio) - thiocarbonyl - thio] - 2 - phenylacetamido]-penicillanic acids are made by acylating 6-amino-penicillanic acid trimethylsilyl ester; the novel antibacterial trimethylsilyl ester of DL-7-[2-[(butylthio)-thiocarbonylthio] - 2 - phenylacetamido] - cephalosporanic acid is also prepared.
