Azido-Alkyl/Aryl Acids

Azido-Alkyl/Aryl Acids

Azides can undergo a Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuAAC) to afford 1,4-disubstituted 1,2,3-triazoles. Developed by K. Barry Sharpless and Morton Meldal, this type of chemical transformation was quickly dubbed “Click Chemistry”. It has since become a widely used reaction that is orthogonal to many other types of chemical transformations and is used in various kinds of applications. Besides, azido-functionalized molecules can be used for Staudinger ligation.
