8‐Aminoquinoline: A Powerful Directing Group in Metal‐Catalyzed Direct Functionalization of CH Bonds

Chelate me if you can: Over the last decade, strategies for the functionalization of both C(sp2)-H and C(sp3)-H bonds have witnessed an increasing use of a simple, yet powerful directing group, 8-aminoquinoline (in blue). This auxiliary is very efficient in a wide range of metal-mediated reactions, and can be readily removed to afford the desired carboxylic acids or corresponding derivatives.
