Desired products were obtained in moderate to excellent yields. Similar aminoindolizines products were afforded from trimethylsilyl protected alkyne substrates as well. This methodology provides a rapid access to construct a diversity-oriented library of indolizines.

CuCl catalyzes efficient synthesis of aminoindolizine scaffolds by one-pot reactions in PEG of pyridine- or quinoline-2-carboxaldehydes with secondary amines and terminalalkynes via tandem C–H activation, coupling, and cyclization reactions. The reactions are easy to perform, atom-economic, environment friendly, broad in scope, and allow the generation of a number of biologically potent aminoindolizine
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
