Abstract

A straightforward and industrially feasible synthesis of 7 beta-acylamino-7 alpha-methoxy-3-[(1-methyl-1H-tetrazol-5-ylthio)methyl]-1-oxa-3-cephem-4-carboxylic acid (35) from penicillins is described. Reaction of 6 alpha-acylaminopenicillanate S-oxides with triphenylphosphine gave epioxazolines (16) which were transformed into allylic alcohols (28) via… (More)
