The first total synthesis of (+/-)-psychotrimine, a novel trimeric indole alkaloid isolated from Psychotria rostrata, was achieved. In the total synthesis, the copper-mediated intramolecular and intermolecular aminations of halobenzenes, which respectively contributed to the construction of a pyrrolidinoindoline core and the installation of a third tryptamine unit, were used as key steps.
实现了(+/-)-Psychotrimine的首次全合成,这是一种从Psychotria rostrata分离的新型三聚吲哚生物碱。在整个合成过程中,关键步骤采用了铜介导的卤代苯的分子内和分子间胺化反应,这些胺化反应分别构成了吡咯烷基二氢吲哚核的构造和第三个色胺单元的安装。
