A facile, efficient and mild copper catalyzed strategy for cascade synthesis of various 1,4-disubstituted 1,2,3-triazoles from arylboronic acids, sodium azide and alkynes was developed by using aqueous bile salt NaDC solution as an accelerating medium. Low catalyst loading (only 1 mol% Cu source was sufficient for in situ generation of azide followed by azide–alkyne coupling), green solvent, use of bio-surfactant as additive and short reaction time make this protocol highly accessible and environment friendly.

胆汁盐水溶液加速从芳基硼酸级联合成1,2,3-三唑

通过使用胆汁盐NaDC水溶液作为促进介质，开发了一种简便，高效，温和的铜催化策略，用于从芳基硼酸，叠氮化钠和炔烃级联合成各种1,4-二取代的1,2,3-三唑。低催化剂负载量（仅1 mol％的铜源足以就地生成叠氮化物，然后进行叠氮化物-炔烃偶联反应），绿色溶剂，使用生物表面活性剂作为添加剂以及较短的反应时间使该方案高度可访问且对环境友好。
