Using a new CuI/DMAP catalytic system, oxidative N-alkynylation of 7-azaindole has been discussed. A detailed mechanistic study has been performed based on the reactive intermediate [CuII(DMAP)2I2], supported by both DFT calculations and UV-visible spectroscopy. Further several 7-azaindole decorated 1,4 and 1,5 disubstituted 1,2,3-triazole derivatives has been synthesized via click chemistry.
使用新的 CuI/DMAP 催化体系,讨论了 7-氮杂吲哚的氧化N-炔基化反应。在 DFT 计算和紫外-可见光谱的支持下,基于反应中间体 [Cu II (DMAP) 2 I 2 ] 进行了详细的机理研究。此外,还通过点击化学合成了几种7-氮杂吲哚修饰的1,4和1,5二取代的1,2,3-三唑衍生物。
