Abstract

Preparation procedure, of new cephalosporanic acid derivatives of the formula: **(See formula)** wherein R1 is a nitro group, an alkoxy group, an alkanesulfonamido group or an alkolaminosulfonamido group, R2 is a hydrogen atom or a hydroxyl group, provided that R2 is a hydroxyl group when R1 is a nitro group or an alkoxy group ; R3 is a hydrogen atom or a heterocyclicothio group, in which the heterocyclic group may be substituted with an alcohol group, provided that R3 is a hydrogen atom when R1 is an alkoxy group and R2 is a hydroxyl group; X is an amino group or a protected amino group; M is a pharmaceutically acceptable, non-toxic hydrogen atom or cation; comprising reacting 7-amino-3-cephem-4-carboxylic acids substituted in position 3 of the formula: **(See formula)** wherein R3 and M are as defined above, or their derivatives at the carboxyl and/or amino groups, with substituted phenylglycine of the formula: **(See formula)** wherein R1, R2 and X are as defined above, or their reactive derivatives on the carboxyl group, and, if desired, remove the protecting group from the amino group from the reaction product.
