Post‐Functionalization of Organoboranes by Cu‐Catalyzed Azide Alkyne [3+2]‐Cycloaddition Reaction

Abstract

The copper‐catalyzed azide alkyne [3+2]‐cycloaddition (CuAAC) reaction of organoboranes represents an attractive area of research within the field of click chemistry, with diverse applications in organic synthesis, medicinal chemistry, or materials science. Despite the potential issues caused by the copper insertion into the carbon‐boron bond, significant progress has been made to harness the reactivity of organoboron compounds in CuAAC. This review provides an overview of the catalytic methods reported for CuAAC with various organoboranes, discussing the stability of the boron group and highlighting recent advancements in this area.
