We have developed a one-iridium-catalyst system that transforms N-allyl-N-sulfonyl-2-(silylalkynyl)aniline derivatives, which are 1,7-enynes in which both multiple bonds have a heteroatom, to the corresponding substituted indole derivatives via isomerization/cycloisomerization/aromatization. This strategy provides an atom-economical and straightforward synthetic approach to a series of valuable indoles
我们开发了一种单铱催化剂系统,可将N-烯丙基-N-磺酰基-2-(甲硅烷基炔基)苯胺衍生物(即 1,7-烯炔,其中两个多键均具有一个杂原子)转化为相应的取代吲哚衍生物通过异构化/环异构化/芳构化。该策略为一系列在 2 位和 3 位具有乙烯基和甲硅烷基甲基的有价值的吲哚提供了一种原子经济且直接的合成方法。
