iodine(III)-mediated intramolecular dearomative spirocyclization of indole derivatives to generate highly strained spirocyclobutyl, spirocyclopentyl, and spirocyclohexyl indolenines in moderate to good yields. A set of structurally novel, densely functionalized spiroindolenines with broad functional group compatibility was efficiently constructed in this way under mild reaction conditions. Moreover
在此,我们报告了一种新型的碘 (III) 介导的吲哚衍生物的分子内脱芳环化螺环化,以中等至良好的收率生成高度应变的螺环丁基、螺环戊基和螺环己基吲哚啉。在温和的反应条件下,以这种方式有效地构建了一组具有广泛官能团相容性的结构新颖、密集官能化的螺吲哚。此外,β-烯胺酯作为产品中的多功能官能团,为生物活性化合物及相关天然产物的合成提供了极大的便利。
