A facile synthesis of 5-amino-[1,2,3]triazolo[5,1-a]isoquinoline derivatives through copper-catalyzed cascade reactions

Abstract

A copper-catalyzed cascade method was developed for the synthesis of [1,2,3]triazolo[5,1-a]isoquinoline derivatives. The N-fused heterocycles were obtained in good to excellent yields under mild conditions, which provided a new strategy for the preparation of this highly functionalized building block.
