A robust and versatile protocol for synthesis of 1-monosubstituted and 1,4-disubstituted 1H-1,2,3-triazoles was established under continuous flow conditions using copper-on-charcoal as a heterogeneous catalyst. This methodology allowed for the synthesis of a diverse set of substituted 1,2,3-triazoles with good functional group tolerance and high yields. 2-Ynoic acids were also used as small-chain alkyne
在连续流动条件下,使用铜-炭作为非均相催化剂,建立了一种用于合成 1-单取代和 1,4-二取代 1 H -1,2,3-三唑的稳健且通用的方案。该方法允许合成具有良好官能团耐受性和高产率的多种取代的 1,2,3-三唑。2-Ynoic酸也被用作脱羧/环加成级联中的小链炔烃供体,允许绕过气态试剂,以高产率提供所需的三唑。所开发的方法用于合成一种抗癫痫剂 Rufinamide,其分离产率为 96%。
