A novel synthetic route to the hexacyclic system of trigonoliimine A was accomplished in four steps from N-phthaloyl 6-OMe-tryptamine. Key reactions include a three-component Strecker-type reaction to fashion the two C–N bonds in the D ring and a subsequent Houben–Hoesch type cyclization to deliver the characteristic seven-membered C ring.
从N-邻苯二甲酰基6-OMe-色胺开始的四个步骤完成了一条合成三角叶精亚胺A六环系统的新途径。关键反应包括在D环上形成两个C–N键的三组分Strecker型反应,以及随后的Houben–Hoesch型环化反应,以提供特征性的七元C环。
