Report here is the development of a [5 + 2 + 1]/ene strategy for the synthesis of molecules with linear tricyclic 5/5/5 and 6/5/5 skeletons widely found in natural products. The first step of this strategy is applying a Rh-catalyzed [5 + 2 + 1] reaction of ene-vinylcyclopropanes and CO to synthesize 5/8 and 6/8 bicyclic compounds, which can then be transformed to the final target molecules by an InCl₃-catalyzed ene reaction.

通过 [5 + 2 + 1]/Ene 策略合成具有线性三环 5/5/5 和 6/5/5 骨架的分子

这里的报告是开发 [5 + 2 + 1]/ene 策略，用于合成具有广泛存在于天然产物中的线性三环 5/5/5 和 6/5/5 骨架的分子。该策略的第一步是应用 Rh 催化的烯-乙烯基环丙烷和 CO 的 [5 + 2 + 1] 反应合成 5/8 和 6/8 双环化合物，然后可以通过以下方式将其转化为最终目标分子InCl _{3 -}催化的烯反应。
