Title: N-deacylation of 7-acylamido-3-hydroxymethyl cephalosporins
IPC: C07D501/26
Filed: 1974-07-31
Abstract: A process for the N-deacylation of 7-acylamido-3-hydroxymethylcephalosporins, in which, in a multi-stage process, the 7-amino group is liberated and the hydroxyl group in the 3-hydroxymethyl group is replaced by a halogen atom. First, the starting compound is reacted with an imide-halide-forming reagent in the presence of a base and thereafter the imide-halide formed is reacted with an iminoether-forming compound, after which the iminoether thus obtained is cleaved hydrolytically. The products of the process may be used as starting material or as precursors for the preparation of antibiotically active cephalosporins. To prepare cephaloridine and cefalozine, the product of the process is first N-acylated in an appropriate manner, after which the halogen atom in the 3-halogenomethyl group is replaced by the appropriate radical.
