A new reaction system with CuCl as catalyst, TEA as base and O2/chloramine-T as oxidant was developed for one-pot in situ oxidative-coupling to synthesize 5-aryl-1,4-disubstituted 1,2,3-triazoles in this paper. A variety of 5-arylated-1,2,3-triazole compounds could be efficiently prepared directly from the readily accessible organic azides, terminal alkynes and arylboronic acids. Advantages of the
建立了以CuCl为催化剂、TEA为碱、O 2 /氯胺-T为氧化剂的一锅法原位氧化偶联合成5-芳基-1,4-二取代1,2,3-三唑的新反应体系。在本文中。各种5-芳基化-1,2,3-三唑化合物可以直接从容易获得的有机叠氮化物、末端炔烃和芳基硼酸有效地制备。该方法的优点包括使用低成本催化剂、清洁氧化剂、毒性较小的添加剂和低反应温度。重要的是,由于避免了苛刻的强碱性试剂和高温,所提出的方法可以为从设计的结构复杂的带有天然产物基序的炔基或叠氮化物供体多组分合成5-芳基-1,2,3-三唑提供温和的条件和敏感的官能团。
