    一种新的手性甘氨酸衍生物——(R)-和(S)-叔丁基2-叔丁基-4-甲氧基-2,5-二氢咪唑-1-羧酸酯(BDI)的制备和在氨基酸合成中的应用
    摘要:
    标题化合物 BDI 以多克规模制备,方法是通过非对映体盐(方案​​ 2)拆分前体 2-叔丁基咪唑烷-4-酮(来自甘氨酸酰胺和新戊醛),或通过手性柱上的制备色谱对映异构体分离。锂化 BDI 衍生物是高度亲核物质,结合了烯酸锂、烯醇醚和 N-Boc-烯酸 (E, G) 的结构元素。它们以完全非对映选择性(NMR 分析)从反式到叔丁基进行反应。所使用的亲电子试剂是伯和仲烷基、烯丙基、苄基和炔丙基卤化物(方案 3 和 5)、烯酸酯(在迈克尔加成中,方案 7)以及脂肪族和芳族醛(在羟醛加成中,方案 8)。当在这些反应中形成第三个环外立体中心时,存在高度的对映异构体分化(使用外消旋卤化物,产品 10-12)和对映体表面分化(使用烯酸酯和醛,产品 40-50)。反应是如此干净,以至于高效的原位双烷基化是可行的,其中两种不同亲电试剂的添加顺序决定了新形成的立体中心的构型(方案 5)。与先前报道的手性甘氨酸试剂的衍生物相比,BDI
