A simple and efficient method for the synthesis of α-branched amines through formal oxidative C–H functionalization is reported. A commercially available quinone organocatalyst is employed to promote the aerobic oxidation of primary amines to the corresponding N-protected imines, which are then trapped in situ with an appropriate nucleophile to give access to versatile functionalized amines in good to excellent yields (70–90 %).

Paragraph 0293; 0295, (2015/03/16)
The present invention relates to an iridium-based catalyst compound for hydrogenating reducible moieties, especially imines and iminiums, the catalyst compounds being defined by the formula: (Formula (I)) where ring B is a conjugated ring system with one or more substituents. The catalysts of the invention are particularly effective in reductive amination procedures which involve the in situ generation of the imine or iminium under reductive hydrogenative conditions.
