摘要

A METHOD FOR THE ACILATION OF THE 7-AMINO GROUP OF THE CEPHALOSPORANIC RING IS PRESENTED, IN ACCORDANCE WITH WHICH A PROTECTED ADDUCTOR OF TIAZOLIL OF AMINO 7-ACA IS PREPARED BY ACIDATING SUCH A GROUP OF AMINO-AYAIL, Amino Acid. BEEN PROTECTED THROUGH A GROUP OF PHENYL ACETYL OR PHENOXY ACETYL, THEN THE AMINO GROUP DEPLOYED THROUGH WATER HYDROLYSIS IN THE PRESENCE OF A PENICILLIN AMIDASE GO RESPECTIVELY OF A PENICILLIN AMYLASE V.
