CAS:80544-17-8|(Z)-2-(Methoxycarbonylmethoxyimino)-2-(2-aminothiazol-4-yl)acetic Acid

Introduction and application of CAS:80544-17-8|(Z)-2-(Methoxycarbonylmethoxyimino)-2-(2-aminothiazol-4-yl)acetic acid

Purpose (Z)-2-(2-amino-4-thiazolyl)-2-methoxycarbonylmethoxyiminoacetic acid (cefixime side chain acid) is an important side chain acid for the synthesis of third and fourth generation cephalosporins. chain intermediates, strengthening their research and development has great economic and practical value. The synthesis of cefixime side chain acid is based on tert-butyl acetoacetate as raw material, and through the steps of oximation, etherification, chlorination, cyclization and hydrolysis, (Z)-2-(2-aminothiazole- 4-yl)-2-methoxycarbonylmethoxyiminoacetic acid.
