A simple and efficient one‐pot microwave‐assisted click formation of 1‐(substituted)‐1H‐1,2,3‐triazol‐4‐yl)methyl)diphenylphosphineoxide derivatives via Huisgen regioselective [3+2]‐cycloaddition of an in situ generated organic azides and diphenyl(prop‐2‐yn‐1‐yl)phosphine oxide in highly polar DMSO‐H2O medium. This synthetic protocol is mild, requires shorter reaction time, and afforded products in
通过Huisgen区域选择性[3 + 2]-环加成一个简单且有效的单锅微波辅助点击形成1-(取代)-1 H -1,2,3-三唑-4-甲基)二苯基膦氧化物衍生物在高极性DMSO-H 2 O介质中原位生成有机叠氮化物和二苯基(prop-2-yn-1-基)氧化膦。该合成方案温和,需要更短的反应时间,并以高产率提供具有高区域选择性的产物。
