Herein, a gold-catalyzed cascade reaction of yne-enones with iminooxindoles has been developed through a cascade cycloisomerization/(3 + 2) annulation process. This approach provides a straightforward and efficient route for the synthesis of functionalized 3,2′-pyrrolidinyl-spirooxindoles in high reactivity and broad substrate scope with excellent cis-selectivity. Moreover, the subsequent functionalization
在此,通过级联环异构化/(3 + 2)环化过程开发了金催化的炔烯酮与亚氨基氧吲哚的级联反应。该方法为合成功能化 3,2'-吡咯烷基-螺吲哚提供了一种简单有效的途径,具有高反应活性、广泛的底物范围和优异的顺式选择性。此外,呋喃单元的后续官能化允许螺吲哚衍生物的多样化合成,这些衍生物已表现出良好的抗肿瘤活性。
