Abstract
A procedure for the preparation of new cephalosporanic acid derivatives of the formula **(See formula)** where 1 is an alkanesulfonamido group; R2 is a hydrogen atom; R3 is a heterocyclic-thio group, in which the heterocyclic group may be substituted with an alcohol group; X is an amino group or a protected amino group; and M is a pharmaceutically acceptable, non-toxic hydrogen atom or cation; which comprises reacting 7-phenylglyomino amino-3-alloanoyloxymethyl-3-oephem-4-carboxylic acids of the formula **(See formula)** in which R1', R2 X and M are as defined above, and R3''is an alkanoyl group, with thioacoholic compounds of the formula R3'- H wherein Ry is as defined above, or its alkali metal salts, and separating, if desired, the protecting group from the amino group from the reaction product.
