摘要

提出了一种可见光介导无金属、无氧化剂磷酸催化合成2-selanyl NHCbz-tryptamine/3-取代吲哚的新方法。这种直接的C-2硒化策略，在良好的环境条件下，通过色胺/3-取代吲哚和二芳基/二烷基硒化反应，可以获得广泛的2-芳基/烷基色胺基nhcbz色胺/3-取代吲哚。通过紫外可见法、循环伏安法和对照实验对其机理进行了深入的研究。

Visible-Light-Induced Metal-Free Selenation of Tryptamines/3-Substituted Indoles

Visible light mediated novel metal-free, oxidant free phosphoric acid catalysed method for the synthesis of 2-selanyl NHCbz-tryptamine/3-subtituted indole is presented. This direct C-2 selenation strategy, with environmental benign conditions by reaction of tryptamine/3-substituted indole and diaryl/dialkyl selenide, allows access to a wide range of 2-aryl/alkyl selanyl NHCbz-tryptamines/3-substituted indoles. An experimental investigation using UV-Vis, Cyclic voltammetry and controlled experiments sheds insight on the plausible mechanism.
