Brönsted acid-catalyzed one-pot synthesis of indoles from o-aminobenzyl alcohols and furans has been developed. This method operates via the in situ formation of aminobenzylfuran, followed by its recyclization into the indole core. The method proved to be efficient for substrates possessing different functional groups, including −OMe, −CO2Cy, and −Br. The resulting indoles can easily be transformed
已经开发出布朗斯台德酸催化从邻氨基苯甲醇和呋喃一锅合成吲哚的方法。该方法通过原位形成氨基苄基呋喃,然后将其再循环到吲哚核心中来进行。该方法被证明对于具有不同官能团的底物是有效的,包括-OMe、-CO 2 Cy和-Br。所得吲哚可以很容易地转化为不同的支架,包括2,3-和1,2-融合吲哚,以及在C-2位置具有α,β-不饱和酮部分的吲哚。
