Abstract

A procedure for the transposition of a 6-acylamidopenicillanico acid sulfoxide to 7-acilamido3-methylcef-3-em-4-carboxylic acid by heating said phenycylanic acid sulfoxide in the presence of an acid catalyst, whose process is characterized by heating the acid form free from 6-acylamidopenicillanic acid sulfoxide in a weakly basic solvent, in the presence of a catalyst comprising a strong acid either alone or in combination with a nitrogenous base with a pKb of not less than 4.
