7α-METHOXYLATION OF CEPHALOSPORINS

A method for 7α-methoxylation of cephalosporins is described.Treatment of the imidoyl chlorides of cephalosporins (2) with 4-methoxypyridine N-oxide afforded (4-pyrido-1-yl)oxyimino compounds (3), which were transformed to 7α-methoxycephalosporins (4) via thermal 1,4-elimination followed by addition of methanol.
