The (±)-pentalenene 1 and (±)-epi-pentalenene 12 have been synthesised by a novel spiro-annulation strategy that allowed the subsequent formation of two of the five-membered rings by aldol condensations; the order of reduction of two double bonds in a bicyclic intermediate 8 led, in a Stereoselective manner, to one C-9 epimer or the other.
通过一种新颖的螺环化策略合成了(±)-五亚甲基1和(±)-表五亚甲基12,该策略允许通过醛缩合反应形成五个成员环中的两个环;通过双环中间体8中两个双键的还原顺序,以立体选择性方式形成C-9的两种对映异构体。
