A highly efficient procedure for preparing 2-acylpyrroles and its derivatives is described. The products were obtained through regioselective Friedel–Crafts reactions of pyrroles and its derivatives with alkyl or aryl acid chlorides catalysed by zinc oxide under solvent-free conditions. This method has the advantages of green chemistry, operational simplicity, solvent-free conditions, and recoverable catalyst.
本文介绍了一种高效制备 2-酰基吡咯及其衍生物的方法。在无溶剂条件下,通过氧化锌催化吡咯及其衍生物与烷基或芳基酸氯化物的弗里德尔-卡夫斯(Friedel-Crafts)区域选择性反应,获得了这些产物。该方法具有绿色化学、操作简单、无溶剂条件和催化剂可回收等优点。
