| titleOfInvention | oxidation process for preparing 3-formyl cefem derivatives |
| abstract | Oxidation process for preparing 3-formyl cefem derivatives. The present invention relates to an improved process for oxidizing 3-hydroxymethyl-cephem derivatives to the corresponding 3-formyl-cephem derivatives. in particular, this oxidation process is for the preparation of 7- [2- (5-amino [1,2,4] thia-diazol-3-yl) -2-hydroxyimino-acetylamino] -3-formyl acid derivatives -8-oxo-5-thia-1-aza-bicyclo [4.2.0] oct-2-ene-2-carboxylic formula (i) using a combination of a 10-type hypervalent iodine oxidizing agent i-3 such as bis (acetoxy) iodo-benzene (baib) and a catalyst such as 2,2,6,6-tetramethyl-1-piperidinyloxy (time). These compounds of formula (I) are intermediates in the synthesis of ceftobiprol. |
