The combination of CuI and glycerol exhibits a versatile and high catalytic activity in the Huisgen cycloaddition of azides and terminal or 1-iodoalkynes under standard bench experimental conditions (room temperature, under air and in the absence of a base) providing a pivotal contribution to Green Chemistry. Since the catalytic reaction: (i) is amenable at low catalyst loading and accessible on a high scale; (ii) tolerates a variety of functionalities (including the presence of a free thio moiety in the substrate); (iii) can be effectively recycled (up to 6 consecutive runs); and (iv) is isolated in a straightforward manner (by simple filtration in the absence of organic solvents at any stage of the synthesis), the practical application of this methodology provides a complementary synthetic tool to the familiar CuAAC reactions.
在标准实验条件下(室温、空气和无碱条件下),CuI 和
甘油的组合在
叠氮化物和末端或 1-iodo 烷炔的 Huisgen 环加成反应中表现出多功能和高催化活性,为绿色
化学做出了重要贡献。由于该催化反应:(i) 适合于低催化剂负载和大规模使用;(ii) 可容忍多种官能团(包括底物中存在游离
硫代分子);(iii) 可有效循环使用(最多连续运行 6 次);(iv) 可直接分离(在合成的任何阶段均不使用有机溶剂的情况下通过简单过滤),因此该方法的实际应用为我们熟悉的 Cu
AAC 反应提供了一种补充合成工具。
