The compact tricyclic substructure of solanoeclepin A containing the cyclobutanone ring was prepared by using as the key step a highly regioselective intramolecular [2 + 2]-photocycloaddition reaction between one of the [small pi]-bonds of an allene and the CC double bond of a butenolide.
索拉诺穿心莲内酯A的紧密三环亚结构含有环丁酮环,其制备过程的关键步骤是在丙二烯的一个[小π]键与丁烯内酯的碳碳双键之间进行高度区域选择性的分子内[2 + 2]光环化加成反应。
