Synthesis method of cefamoxef sodium

The invention relates to a synthesis method of latamoxef sodium. The synthesis method specifically comprises the following steps: reacting an oxygen cephalosporin mother nucleus 1 with 1-methyl-5-mercaptotetrazole sodium salt to obtain a compound 2, carrying out deprotection to obtain a compound 3, adding methoxyl and a 7-site side chain on the compound 3 to obtain a compound 5, and then, carryingout final deprotection on the compound 5 to obtain high-purity latamoxef sodium. The method provided by the invention is high in yield, mild in condition and environment-friendly; enzyme is used fordeprotection and condensation reaction, so that high-toxicity and high-corrosivity reagents are avoided; and the high-purity latamoxef sodium is obtained at a high yield.
