General synthesis of (1-substituted-1H-1,2,3-triazol-4-ylmethyl)-dialkylamines via a copper(I)-catalyzed three-component reaction in water

A copper(l)-catalyzed three-component reaction to form (1 -substituted- 1H- 1,2,3-triazol-4-ylmethyl)-dialkylamines based on the Huisgen cycloaddition using amine, propargyl halide and azide in water was proposed. The process showed considerable synthetic advantages in terms of high atom economy, low environmental impact, atmospheric oxygen, wide substrate scope, mild reaction condition and good yields.
