A novel solvent-directed click reaction between active methylene compounds and azido-1,3,5-triazines has been developed. In aqueous solution, the regiospecific trisubstituted 1,2,3-triazole products are quickly synthesized in high yields under mild conditions and easy to separate without column chromatography. This click reaction is controlled by the protonation of a nitrogen anion intermediate, and
已开发了一种活性亚甲基化合物与叠氮基1,3,5-三嗪之间新型的溶剂定向点击反应。在水溶液中,区域特异性的三取代的1,2,3-三唑产物在温和的条件下可以高产率快速合成,无需柱色谱即可轻松分离。该点击反应由氮阴离子中间体的质子化控制,并且通过DFT计算证实了推测的机理。
