PROCESS FOR THE PRODUCTION OF ACID 7BA ((2D-2-AMINO-2-CARBOXY) ETHYLTHIOACETAMIDO) -7A-METHOXY-3 - ((1-METHYL-1H-TETRAZOLE-5-YL) THIOMETHYL) -3-CEPHEM- 4-CARBOXYLIC |
| abstract |
THE PROCESS FOR THE PRODUCTION OF THIS CEPHAMYCIN DERIVATIVE IS CARRIED OUT ECONOMICALLY AND EFFICIENTLY FROM CEPHAMYCIN A AND / OR CEPHAMYCIN B; IT CONSISTS OF THE CONSECUTIVE STEPS IN THE REACTION OF CEPHAMYCIN WITH 5-MERCAPTO-1-METHYL-1H-TETRAZOLE, PROTECTION OF THE AMINO TERMINAL GROUP BY ACYLATION, PROTECTION OF TWO CARBOXYL GROUPS BY ESTERIFICATION, REPLACEMENT OF THE ACINO GROUP 7 BY A HALOGENOACETYL GROUP, DEPROTECTION OF THE CARBOXYL GROUP BLOCKED IN 4 AND CONDENSATION OF D-CYSTEIN WITH THE HALOGENOACETYL GROUP LINKED TO THE AMINO EN7 GROUP. |
