Improved process for preparing cephalosporins |
| abstract |
The invention relates to an improved process for preparing cephalosporins by reaction compounds such as 7-amino -cephalosporanic acid, 7-amino-3-deacetoxy-cephalosporanic acid or their derivatives with derivatives of a-amino acids in the presence of a properly immobilized penicillin acylase enzyme under the following conditions, independently, or in combination : (1) at a temperature ranging from 0°C to +20°C; or (2) at ambient pH ; with a high molar ratio of (a-amino acid to a cephalosporanic nucleus. |
