simple and efficient continuous-flow procedure is reported. The 1,3-dipolar cycloaddition reactions were performed with copper powder as a readily accessible Cu(I) source. Initially, high reaction rates were achieved under high-pressure/high-temperature conditions. Subsequently, the reaction temperature was lowered to room temperature by the joint use of both basic and acidic additives to improve the safety
报道了以简单有效的连续流动程序制备新型多取代 1,2,3-三唑改性 β-氨基环己烷羧酸衍生物。1,3-偶极环加成反应是用铜粉作为容易获得的 Cu(I) 源进行的。最初,在高压/高温条件下实现了高反应速率。随后,通过联合使用碱性和酸性添加剂将反应温度降至室温以提高合成的安全性,因为叠氮化物将作为不稳定的反应物处理。还进行了放大实验,从而以安全和直接的方式实现了克级生产。得到的 1,2,
