| titleOfInvention | 7-Phenylacetamido-3-deacetoxycephalosporanate and its preparation method and application |
| abstract | The present invention relates to 7-phenylacetamido-3-deacetoxy cephalosporanate and its preparation method and application. Described 7-phenylacetamido-3-deacetoxy cephalosporanate, its structural formula is as follows: wherein M + is selected from metal ions or ammonium ions. A method for preparing 7-phenylacetamido-3-deacetoxy cephalosporanic acid salt, comprising the steps of: reacting 7-phenylacetamido-3-deacetoxy cephalosporanic acid with an alkaline salt-forming agent to obtain; Or by reacting 7-phenylacetamido-3-deacetoxy cephalosporanic acid trimethylsilyl ester with an alkaline salt-forming agent. 7-ADCA can be prepared from 7-phenylacetamido-3-deacetoxycephalosporanate, and the content of the obtained 7-ADCA product is very high, especially the content of the isomer △2-7-ADCA Below 0.5%, it is more suitable for synthesizing high-quality cephalosporin APIs such as cephalexin, cefradine, cefadroxil, and ceftazime pivoxil. |
