摘要
以1-(2-叔丁氧基羰酰胺唑-4-基)-1(Z)-戊烯酸(1)为原料,经甲基磺酰氯酰化后,与羟甲基-7-氨基头孢烷酸(7-HACA)反应合成了一种头孢卡品中间体7-[1-(2-叔丁氧基酰胺唑-4-基)-1(Z)-戊烯酰胺]-3-羟甲基-3-头孢烯-4-羧酸(3),总收率90.2%,产物结构经1H NMR,IR和MS表征。
A intermediate of Cefcapene 7-[1-(2-tert.-butoxycarbonylaminothiazol-4-yl)-1(Z)-pentencarboxamido]-3-hydroxymethyl-3-cephem-4-carboxylic acid in overall yield of 90.2% was synthesized by acidylation of 1-(2-tert.-butoxycarbonylaminothiazol-4-yl)-1(Z)-pentencarboxylic acid with methanesulphonyl chloride,then combination with hydroxymethyl-7-amino-cephalosporanic acid.The structure of product were confirmed 1H NMR,MS and IR.
