The development of original strategies for the preparation of indole derivatives is a major goal in drug design. Herein, we report the first straight access to indoles from anilines and ethylene glycol by heterogeneous catalysis, based on an acceptorless dehydrogenative condensation, under noninert conditions. In order to achieve high selectivity, a combination of Pt/Al2O3 and ZnO have been found to
制备吲哚衍生物的原始策略的开发是药物设计的主要目标。本文中,我们报告了在非惰性条件下,基于无受体脱氢缩合反应,通过非均相催化从苯胺和乙二醇中首次直接获得吲哚。为了获得高选择性,已经发现Pt / Al 2 O 3和ZnO的组合物使乙二醇缓慢脱氢,在与胺缩合和互变异构平衡之后,生成相应的吡咯环未取代的吲哚。

Chiral Brønsted acid-catalyzed Friedel–Crafts alkylation of electron-rich arenes with in situ-generated ortho-quinone methides: highly enantioselective synthesis of diarylindolylmethanes and triarylmethanes
Hydrogen-bonded, in situ-generated ortho-quinone methides undergo highly enantioselective Friedel–Crafts reactions with indoles and naphthols under mild reaction conditions.
