Microwave assisted one pot three component synthesis of propargylamine, tetra substituted propargylamine and pyrrolo[1,2-a]quinolines using CuNPs@ZnO–PTh as a heterogeneous catalyst

Abstract

A Cu@ZnO–PTh nanocomposite was synthesized and used as a heterogeneous catalyst for KA2 and A3 coupling, which is a highly efficient and green technique.
