Abstract
A method for the acylation of the 7-amino group of the cephalosporanic ring, according to which a 7-ACA amino thiazolyl protected adduct is prepared by acylating said amino group by an aminothiazolyl acetic acid whose amino group has been protected by a phenyl acetyl or a phenoxy acetyl group, the amino group being then deprotected by aqueous hydrolysis in the presence of penicillin G amidase or respectively penicillin V amidase.
