A dinuclear Cu(OAc)2-anchored SBA-15 silica was synthesized, confirmed and showed excellent catalytic activity for the azide–alkyne cycloaddition reaction in water.
PVC-supported ethylenediamine-copper(II) complex: a heterogeneous, efficient, and eco-friendly catalyst for multi-component synthesis of 1,2,3-triazoles by reaction of propargyl bromide, aromatic azides, and amines in water
activity in the multi-component synthesis of 1,4-disubstituted 1,2,3-triazoles by the click reaction of propargyl bromide, aromatic azides, and amines at room temperature. The advantages of this method are high reaction yield, short reaction time, and capability of recovering and reusing the catalyst. In addition, water, as a green medium, is used not only in the synthesis of 1,2,3-triazoles but also in

In this Letter, an efficient strategy for the fast construction of 108 compounds library was developed using click chemistry. The fingerprint of inhibitory activity toward MAO-A/B against this library was obtained, and four hit compounds were identified as selective inhibitors toward MAO-A. Docking study was carried out to demonstrate the binding mode between a9 and MAO-A/B, and the result reveals that a9 localized in the 'aromatic cage' and oriented to establish pi-pi stacking interactions with Tyr407, Tyr444 and FAD in MAO-A rather than in MAO-B.

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.
