ZnI2 was found to be an efficient catalyst for the synthesis of indolizine derivatives by a three-component coupling of pyridine-2-carboxaldehyde/quinoline-2-carboxaldehyde, secondary amines, and terminal alkynes in high yields. This protocol is compatible with a wide range of substrates and is expected to find broad applications due to its operational simplicity, shorter reaction time and low cost
发现ZnI 2是通过吡啶-2-羧醛/喹啉-2-羧醛,仲胺和末端炔烃的三组分偶联以高收率合成吲哚嗪衍生物的有效催化剂。该协议可与多种基材兼容,并且由于其操作简便,反应时间短和成本低廉,有望被广泛应用。初步的光物理研究表明,合成的吗啉代吡咯并[1,2- a ]喹啉代表了一类新的具有高量子产率的荧光团。
