Asymmetric 1,3-Dipolar Cycloadditions

Tetrahedron, 2007
This review is intended to update the recent developments in asymmetric 1,3-dipolar cycloaddition reactions involving a variety of heteroylides (or ylide equivalents) and dipolarophiles, covering the literature from 2001 to 2006. Figure options Download

Peptidotriazoles on solid phase: [1,2,3]-triazoles by regiospecific copper(i)-catalyzed 1,3-dipolar cycloadditions of terminal alkynes to azides.

Journal of Organic Chemistry, 2002
The cycloaddition of azides to alkynes is one of the most important synthetic routes to 1H-[1,2,3]-triazoles. Here a novel regiospecific copper(I)-catalyzed 1,3-dipolar cycloaddition of terminal alkynes to azides on solid-phase is reported.

1,3-dipolar cycloadditions of azides and alkynes: a universal ligation tool in polymer and materials science.

Angewandte Chemie, 2007
In 2001, Sharpless and co-workers introduced "click" chemistry, a new approach in organic synthesis that involves a handful of almost perfect chemical reactions.

1,3-Dipolar Cycloadditions. Past and Future†

, 1963
In contrast to the very large number of special methods applicable to syntheses in the heterocyclic series, relatively few general methods are available. The 1,3-dipolar addition offers a remarkably wide range of utility in the synthesis of five-membered
