Abstract
A procedure for the preparation of 3-halocephalosporins of the formula: ** (See formula) ** where R is hydrogen or an acyl group of the formula ** (See formula) ** where R'is C1-C6 alkyl, C1-C3 haloalkyl cyano C1-C3 alkyl, phenyl, methylphenyl, hydroxyphenyl, halophenyl, nitrophenyl, aminophenyl, methoxyphenyl, 5-amino-5-carboxybutyl or a 5-amino-5-substituted ester group -carboxybutyl of formula: ** (See formula) ** where A is diphenylmethyl, p-nitrophenyl, p-methoxybenzyl, benzyl, tert-butyl or 2,2,2-trichlorethyl and A'is C2-C4 alkanoyl, C2-C4 haloalkanoyl, benzoyl, halobenzoyl, 2,4-dinitrophenyl or phthaloyl; or R'is a group of formula ** (See formula) ** where a and a'are independently hydrogen, C1-C4 lower alkyl, halogen lower alkoxy, hydroxy, nitro, amino or carboxy; Z is oxygen or sulfur; and m is 0 or 1; or R'is a group of formula ** (See formula) ** where P is 2-thienyl, 3-thienyl, phenyl, or a substituted phenyl group of the formula ** (See formula) ** where a and a'are defined above, Q is hydroxy, formyloxy, acetoxy, carboxy, or sulfo; or R'is a group of formula ** (See formula) ** where P has the meaning given above and Y is hydrogen, methyl or acetyl; or R'is a group of formula R'' - CH2- where R'' is 2-thienyl, 3-thienyl, 2-furyl, 2-oxazyl, 2-thiazyl or 1-tetrazyl; or R'is a group of formula where a, a', Z and m have the previously defined meaning; R1 is hydrogen, benzyl, p-methoxybenzyl, p-nitrobenzyl, diphenylmethyl, 2,2,2-trichlorethyl, tert-butyl or a pharmaceutically acceptable ester of the formula: ** (See formula) ** and X is chlorine or bromine; and when R1 is hydrogen, its pharmaceutically acceptable and non-toxic salts; whose procedure is characterized by reacting a compound of formula: ** (See formula) ** where R'is the one defined above and R2 is a forming group of a protective ester of carboxylic acid, a) with a halogenating agent in a solvent capable of forming an iminium halide, optionally followed by b) cleavage of the 7-acylamido side chain and optionally reacylation of the thus obtained 7-amino-3-halocephalosporin compound and c) if desired, remove the carboxylic acid protecting ester forming group to give the corresponding acid.
