提出了一种基于咪唑并[2,1– b ] [1,3]噻唑环系的α-氨基己二酸及其酯杂环类似物的制备方法。在这种方法中,用NBS自由基溴化6-甲基咪唑乙基[2,1- b ] [1,3]噻唑-5-羧酸乙酯提供了一种通用的结构单元,6-溴甲基咪唑乙基[2,1- b ] [ 1,3]噻唑-5-羧酸酯。乙基6-溴甲基咪唑并[2,1– b ] [1,3]噻唑-5-羧酸盐与Schöllkopf的手性助剂偶联,然后经酸水解生成乙基6-[((2 S)‐2‐氨基‐3‐甲氧基-3] [-氧丙基]咪唑[2,1- b] [1,3]噻唑-5-羧酸酯。使用(Boc-氨基)丙二酸二乙酯的类似方法可得到外消旋的2-氨基-3-[(5-乙氧基羰基)咪唑[2,1– b ] [1,3]噻唑-6-6基]丙酸。
