Background

Transition metal-catalyzed amination reactions are amongst the most powerful methods available for accessing the carbon nitrogen based motifs ubiquitously found in medicinal agents and natural products. Recently, efforts have focused on the amination of classically “inert” simple phenolic derivatives to synthesize these structures more readily. Towards this goal, a number of groups have searched for alternative phenol based amination partners, which can be used to direct the assembly of functional groups onto an aromatic ring. Resulting polysubstituted aryl amine motifs are commonly encountered in drug scaffolds, naturally occurring small molecules, pesticides, ligands for catalysis, and materials chemistry. Given the ubiquity of carbon-nitrogen bonds in medicinal agents, more efficient and cost-effective cross-coupling reactions will provide significant economic advantages to therapeutic development and manufacturing.
