A novel and effective Brønsted acid-catalyzed chemoselective synthesis of bis(indolyl)alkanes and 3-alkyl indoles is reported. The selectivity of two significant indole derivatives is attained by allowing the same substrates to go through divergent reaction routes catalyzed by different catalysts. Furthermore, this mild approach is applicable to a wide range of substrates and has high efficacy in large-scale
报道了一种新颖有效的布朗斯台德酸催化化学选择性合成双(吲哚基)烷烃和 3-烷基吲哚。两种重要的吲哚衍生物的选择性是通过允许相同的底物通过不同催化剂催化的不同反应路线来实现的。此外,这种温和的方法适用于广泛的底物,在大规模反应中具有很高的效率。基于对照实验和光谱研究提供了一个合理的机制。
