| titleOfInvention | Intermediates for producing semi-synthetic penicillins |
| abstract | Novel 6-APA, 7-ACA, and 7-ADCA derivatives are described which comprise phosphorylated derivatives of 6-APA, 7-ACA, or 7-ADCA and the corresponding acylated derivatives thereof. The novel compounds are prepared by the reaction of 6-APA, 7-ACA, 7-ADCA or a salt thereof with a phosphorus halide in the presence of an acid acceptor and subsequently acylating the thus formed phosphorylated compound, to form a phosphorylated acylated derivative which upon hydrolysis with water splits off the protective group(s) to provide the corresponding semi-synthetic penicillin or cephalosporin having useful antibacterial activity. |
