of 3-(aminoalkyl)indoles with aryl alcohols and other aromatic nucleophiles through C–N bond cleavage under microwave irradiation to synthesize 3-(α,α-diarylmethyl)indoles. The method uses thiourea as catalyst, which is environmentally benign, water-tolerant and easy to handle. Notably, acid-sensitive substrates are tolerated under the reaction conditions. Thiourea activates the tertiary amine through
我们开发了一种简单有效的方法,用于在微波辐射下通过 C-N 键裂解 3-(氨基烷基)吲哚与芳醇和其他芳香亲核试剂芳基化合成 3-(α,α-二芳基甲基)吲哚。该方法以硫脲为催化剂,对环境无害,耐水,易操作。值得注意的是,在反应条件下可以耐受酸敏感底物。硫脲通过双氢键激活叔胺并将其转化为更好的离去基团。该反应通过形成作为中间体的乙烯基亚胺离子进行。
