Abstract:Ceftibuten belongs to the third generation of oral cephalosporin whose antibacterial spectrum is wide, even effective to Pseudomonas aeruginosa. The pharmacological effect of Ceftibuten was concisely introduced by reviewing the relevant literatures, and the synthetic route of the side chain of Ceftibuten was reported in this paper. The target compound 4-(3-methyl-2-buten-1-oxoacyl)-(Z)-2-(2-phenylacet aminothiazol-4-yl)-2-butenoic acid could be prepared favorably from the starting material ethyl 2-(2-aminothiazol-4-yl) acetate through acylation, hydrolysis, esterification and condensation.The total yield was up to 30% based on ethyl 2-(2-aminothiazol-4-yl) acetate. The products were characterized by IR, MS and 1H NMR.
Key words:cephalosporin;antibacterial activity;side chain;synthesis
