A complete asymmetric synthesis of the orthogonally protected 2-amino-1,3,4-butanetriols I (ABTs: versatile four carbon chiral synthons) was accomplished via the regioselective asymmetric aminohydroxylation (AA) reaction and oxazoline chemistry in four to six steps from the starting olefin 1. The syn-vicinal amino alcohol functionality of I was installed by the regioselective AA reaction of the achiral
正交保护的2-氨基-1,3,4-丁三醇I(ABT:通用的四个碳手性合成子)的完全不对称合成是通过区域选择性不对称氨基羟基化(AA)反应和恶唑啉化学反应从四步到六步完成的起始烯烃1。所述顺式的-vicinal氨基醇官能余物通过非手性的区域选择性反应AA烯烃安装1在一个单一的步骤,和抗的-vicinal氨基醇官能我是从所导出的顺式-氨基醇2通过恶唑啉7的形成和水解反转C2羟基的立体化学。因此,本策略代表了迄今为止最有效,最通用的ABT合成方法。
