Method for synthesizing 3-decarbamoyl-acetyl-cefuroxime acid compound

The invention provides a method for synthesizing a 3-decarbamoyl-acetyl-cefuroxime acid compound. The method comprises the following steps: taking 2-(2-furyl)-2-oxo-acetaldehyde, 7-aminocephalosporanic acid and methoxyamine as raw materials; reacting the raw materials in a reaction solvent under the combined action of a first catalyst, an oxidizing agent and a second catalyst; and carrying out chromatography to obtain the 3-deaminobenzoyl acetyl cefuroxime acid compound. By using the method, the process steps are simple, the byproduct is mainly water, a large amount of other wastes do not exist, and the subsequent treatment cost and the environmental protection pressure are low.
