INTRAMOLECULAR AZIDE-ALKYNE CYCLOADDITION

摘要

The Huisgen 1,3-dipolar cycloaddition is a 'click' reaction that results from the ligation of azides and alkynes to give a triazole moiety. This reaction has been shown to be effective in the formation of a variety of macrocyclic rings. A key point of interest is the regioselectivity and specificity of the cycloaddition. Disclosed herein are specific, selective, and high-yielding methods of azide-alkyne macrocyclization to form 1,4- and 1,5- triazoles and libraries thereof.
