The preparation of penicillins by fermentation is limited to relatively few compounds with side chains derived from mono-substituted acetic acids. The isolation of 6-aminopenicillanic acid (44) either by direct fermentation (37) or enzymic deacylation of penicillin G (38) radically altered this situation. Reacylation of the nucleus with a variety of side chain acids has lead to the preparation of several thousands of new semisynthetic penicillins, many with improved chemotherapeutic properties. In recent years some attention has been directed towards chemical removal of the penicillin side chain, the first successful method being that described by Weissenburger (39) in 1970. A solution of the silyl ester of benzyl-penicillin was converted to the imidate (51) aqueous work-up then provided 6-APA (44). [Pg.13]
