Abstract

A process for the preparation of a synthetic cephalosporin antibiotic, comprising the steps of a) forming a 1-beta-penicillin oxide having a protective ester group in the 3-position; b) converting said δ 3-methyl-cephalosporin ester, and c) removing the side chain in position 7- of said cephalosporin ester, to form a corresponding ester of 7-beta-amino-cephalosporin, characterized in that the ester group the protective agent in the 3-position of penicillin-1-beta-oxide and in the 4-position of the cephalosporin compounds is, throughout the process, a diphenylmethyl ester group, and because then the ester formed is reacted with a acylation reagent to introduce an acyl group in the 7-position and the diphenylmethyl group is removed.
