Abstract
A method of preparing cephalosporin compounds of the formula: **(See formula)** where X is hydrogen, amino or carboxyl; R is phenyl or a 5-membered ring containing one or two heteroatoms, the latter being sulfur, oxygen or nitrogen; A is hydrogen, lower alkanoyl oxy, carbamoyloxy, thiocarbamoyloxy, N-lower alkyl carbamoyloxy, N-lower alkyl thiocarbamoyloxy, N, N-dialkyl lower carbamoyloxy, N, N-dialkyl lower thiocarbamoyloxy, pyridinium, alkylpyridinium, halopyridinium or aminopyridinium and N is sodium, potassium, benzyl, benzohydryl, trimethylsilyl, trichlorethyl, methoxymethyl, hydrogen, benzoylmethyl or methoxybenzyl; whose procedure is to acylate the compound of formula: **(See formula)** where the radicals M'are the same or different and each represents benzohydryl, trimethylsilyl, trichlorethyl, methoxymethyl, benzoylmethyl, methoxybenzyl or benzyl; the acylating agent consists of a substituted acetic acid halide or anhydride of the formula: **(See formula)** where R and X are as defined above and X'is halogen or (see formula); followed by removal of blocking group M'when M is hydrogen or removal of blocking group M' followed by addition of an alkali metal hydroxide when M is sodium or potassium.
