The synthesis of (+)-mesembrine (1) and (+)-mesembranol (2) has been achieved from the monoterpene (S)-(-)-perillyl alcohol. Key transformations include a diastereo- and regioselective Pd-mediated intramolecular Heck reaction, and a double reduction of the resultant cyclic sulfonamide, to afford the cis-3a-aryloctahydroindole skeleton.
(+)-mesembrine(1)和(+)-mesembranol(2)的合成都可由单萜(S)-(-)-perillyl alcohol 实现。关键转化包括立体和区域选择性 Pd 介导的分子内 Heck 反应,以及所得环状磺酰胺的双重还原,从而得到顺式-3a-芳基八氢吲哚骨架。
