Abstract

A semisynthesis process of an antibiotic substance, specifically of the so-called cephaloridin, of the formula: ** (see formula) ** Starting from the 7-amino cephalosporanic acid, of formula: ** (see formula) ** Which is essentially characterized by the fact that the aforementioned substance is obtained by first introducing the alpha-thienyl methyl carbonyl group in the amirate into 7-aminocephalosporanic acid and then directly introducing the pyridinic ring with the help of the catalytic effect of the dispersions of alkali and alkaline earth iodides in pyridine subjected to ultrasonic vibrations.
