PROCEDURE FOR THE PREPARATION OF NEW CEPHALOSPORINS |
| abstract |
PROCEDURE FOR OBTAINING CEPHALOSPORINS OF FORMULA (I), WHERE A, D, E, Y AND R ARE RADICAL DIRECTIVES. IT CONSISTS IN REACTING A COMPOUND OF FORMULA (II) WITH A PIPERIDINE DERIVATIVE OF FORMULA (III), WHERE B IS THE -NCO GROUP OR A REACTIVE DERIVATIVE OF THE -NHCOOH GROUP. THE REACTION IS CARRIED OUT AT A TEMPERATURE BETWEEN -20 AND 50C. AND IN A PH MARGIN BETWEEN 2 AND 9. THE COMPOUNDS OBTAINED IN THIS WAY CAN SUBSEQUENTLY TRANSFORM INTO FREE CARBOXYLIC ACID, IN ITS ESTERS OR IN ITS SALTS. OF APPLICATION AS AN ANTIBIOTIC. |
