| titleOfInvention | Production of novel 7-amino-3-heteroxyclic-thiomethyl-delta3-cephem-4-carboxylic acid |
| abstract | NEW MATERIAL:The compound of formula I (R is lower alkyl) and its salt. n EXAMPLE: 7-Amino-3-(acetonyl-4-pyridiniothiomethyl)-3-cepham-4-carboxylate disulfate. n USE: A medicine. A production intermediate for a cephalosporin compound such as (Z)-7-[α-(2-amino-4-thiazolyl)-α-(methoxyimino)acetamido]-3-(1-acetonyl-4- carboxylate dinitrate) exhibiting excellent antibacterial activity against wide variety of bacterial strains belonging to Gram-positive bacteria and Gram-nega tive bacteria. n PREPARATION: The objective compound of formula I can be produced in high yield and purity on an industrial scale, by reacting 7-amino-cephalosporin compound of formula II or its salt with 2- or 4-thiopyridone or 1-substituted-3- mercatptopyridinium of formula III, formula IV or formula V in chlorosulfonic acid, fluorosulfonic acid or sulfuric acid under cooling or at room temperature. n COPYRIGHT: (C)1988,JPO&Japio |
