Abstract

Azaborines (or borazines) represent an interesting class of heterocycles incorporating a boron–nitrogen structural motif within an aromatic ring system. This creates a system that is isosteric to traditional all-carbon ring systems, as the lone pair on nitrogen can donate into the empty orbital at boron to afford aromatic properties. Reviewed herein are synthetic strategies to access mono- and bicyclic azaborine cores, along with subsequent functionalization strategies, some of which are uniquely applicable due to the inherent dipole imparted on these ring systems.
