Description
技术领域
本发明涉及一种通过不对称转移氢化4-取代-1,2,3,4-四氢吖啶,来合成含三个连续手性中心的四氢喹啉化合物的方法。
技术背景
手性四氢喹啉是许多天然产物和药物分子的关键中间体,广泛地用于材料化学、农药以及医药中间体的合成[1]。因此得到许多科学家的广泛关注,到目前为止,已经发展了一系列方法来合成手性四氢喹啉。但是他们都是主要合成含一个或两个手性中心的四氢喹啉,然而合成含三个连续手性中心的四氢喹啉[2],仍然是有机化学合成中具有一个挑战性课题。
动态动力拆分已经在有机合成中得到广泛的应用,它可以把消旋的底物百分百地转化成手性目标产物[3]。我们在此就是利用动态动力学策略,以手性磷酸为催化剂,1,4-二氢吡啶为氢源实现了4-取代-1,2,3,4-四氢吖啶的不对称转移氢化得到含三个连续手性中心的四氢喹啉化合物。
鉴于手性四氢喹啉化合物在合成化学中的重要意义,发展一种高产率、高立体选择性的方法合成含三个手性中心的四氢喹啉化合物是目前研究的难点和热点。
