TLDR
The copper-catalyzed cycloaddition reaction between azides and alkynes functions efficiently in aqueous solution in the presence of a tris(triazolyl)amine ligand to make rapid and reliable covalent connections to micromolar concentrations of protein decorated with either of the reactive moieties.Abstract:
The copper-catalyzed cycloaddition reaction between azides and alkynes functions efficiently in aqueous solution in the presence of a tris(triazolyl)amine ligand. The process has been employed to make rapid and reliable covalent connections to micromolar concentrations of protein decorated with either of the reactive moieties. The chelating ligand plays a crucial role in stabilizing the Cu(I) oxidation state and protecting the protein from Cu(triazole)-induced denaturation. Because the azide and alkyne groups themselves are unreactive with protein residues or other biomolecules, their ligation is of potential utility as a general bioconjugation method.read more

Cu-catalyzed azide-alkyne cycloaddition.
TL;DR: The basis for the unique properties and rate enhancement for triazole formation under Cu(1) catalysis should be found in the high ∆G of the reaction in combination with the low character of polarity of the dipole of the noncatalyzed thermal reaction, which leads to a considerable activation barrier.

The growing impact of click chemistry on drug discovery.
TL;DR: The copper-(I)-catalyzed 1,2,3-triazole formation from azides and terminal acetylenes is a particularly powerful linking reaction, due to its high degree of dependability, complete specificity, and the bio-compatibility of the reactants.

TL;DR: A chemical transformation that permits the selective formation of covalent adducts among richly functionalized biopolymers within a cellular context is presented and should permit its execution within a cell's interior, offering new possibilities for probing intracellular interactions.

1,3-Dipolar Cycloaddition Chemistry
TL;DR: The theory of 1-3-Dipolar Cycloadditions is discussed in this article. But it does not consider higher-order cycloaddings and higher order cycloreversions.
