Abstract
Procedure for the preparation of derivatives of semi-synthetic cephalosporins and of new suitable intermediates for their preparation, of general formula: **(See formula)** in which R1 is an organic radical other than 4-amino-4-carboxylic-n-butyl acid that may contain alkyl, aryl, aralkyl or heterocyclic groups, and may still have one or more substituents, such as amine, hydroxide or alkoxide, halogen atoms or others; R2 is an organic radical derived from the substrate used chosen from the group 4-amino-4-carboxylic acid -n-butyl, benzyl, phenoxymethyl, 2-pentenyl, pentanyl, heptanyl or para-hydroxy-benzyl; X is a hydrogen atom or an organic radical that can be hydroxide, acyloxide, heterocycloxide, or an amine residue and E can be hydrogen or a protecting group for the carboxylic acid function characterized by acylating on the nitrogen atom of group 7 - acylamine a cephalosporin of general formula: **(See formula)** wherein R2 and X have the previously defined meanings, or a derivative thereof with the protected carboxylic acid function.
