| titleOfInvention | Preparation of cefalosporins intermediates and conversion of said intermediates into active compound precursors |
| abstract | There is described the preparation of the new 7β-[(2-aminothiazol-4-yl)glyoxylamido-3-hydroxymethyl-2-cephem-4-carboxylic acid derivatives, in which the amino group is free or protected by a removable group, and the subsequent conversion of the compounds thus obtained into active cephalosporin precursors either by esterification of the hydroxy group or replacement of the hydroxy group by a halogen atom and, in the latter case, by subsequent replacement of the halogen atom of said 7β-[(2-aminothiazol-4-yl)glyoxylamido-3-halomethyl-3-cephem-4-carboxylic acid derivatives by the residue of a nucleophilic compound to obtain corresponding, immediate precursors of 7β-[α-(2-aminothiazol-4-yl-α-methoxyimino]acetamido-3-(substituted)methyl-3-cephem-4-carboxylic acid derivatives. |
