Abstract Herein, we first time developed a simple, readily available, clean and efficient CuCN/[bmim][PF6] system for the one-pot synthesis of 3-aminoindolizines using commercially available starting materials which included pyridine-2-carbaldehyde, secondary amines, and terminal alkynes. As well, the CuCN/[bmim][PF6] system was reused six times without any appreciable change in its activity.
摘要 在此,我们首次开发了一种简单、容易获得、清洁和高效的 CuCN/[bmim][PF 6 ] 系统,用于一锅法合成 3-氨基中氮茚,使用包括吡啶-2-甲醛、仲胺在内的市售起始原料。和末端炔烃。同样,CuCN/[bmim][PF 6 ] 系统重复使用了六次,其活性没有任何明显变化。
