pumiliotoxin C is described, based on the preparation of an octahydroquinoline derivative through a four-component reaction. The route proceeds in 66% overall yield from 1,3-cyclohexanedione and includes two hydrogenation steps, whose stereochemical outcome was controlled via nitrogen acylation.
基于通过四组分反应制备八氢喹啉衍生物,描述了一种短程且高度非对映选择性的两栖生物碱磷毒素C的合成。该路线从1,3-环己二酮的总收率达到66%,并包括两个氢化步骤,其立体化学结果通过氮酰化来控制。
