磁性Fe 3 O 4纳米粒子:高效且可回收的纳米催化剂,可在无溶剂条件下合成聚氢喹啉和Hantzsch 1,4-二氢吡啶
摘要:
报道了在无溶剂条件下使用磁性Fe 3 O 4纳米颗粒(Fe 3 O 4 MNPs)作为可循环利用催化剂高效,快速合成生物活性取代的Hantzsch 1,4-二氢吡啶和聚氢喹啉衍生物的绿色方法。通过FT-IR,XRD和TEM分析对催化剂进行了表征。与经典反应相比,该方法始终具有反应时间短,催化剂负载少,收率高,易于磁分离和催化剂可重复使用的优点。

A fast and highly efficient copper-catalyzed multicomponent synthesis of 1,4-dihydropyridines under microwave irradiation is described. The protocol utilizes mild reaction conditions with low catalytic loading, leading to high yields. This methodology provides us with biologically active 1,4-dihydropyridine library for medicinal chemistry applications.
