Synthesis and characterization of bisoxazolines- and pybox-copper(<scp>ii</scp>) complexes and their application in the coupling of α-carbonyls with functionalized amines
[(Dm-Pybox)CuBr2] is efficient in catalyzing α-amination of ketones and esters, which tolerates functionality on the carbonyl and amine reaction components.
synthesis of α-amino ketones via the oxidative cross-dehydrogenative coupling of ketones and secondary amines has been developed. The electrochemistry performs in a simple undivided cell using NH4I as a redox catalyst and a cheap graphite plate as electrodes under constant current conditions. Gram-scale reaction demonstrates the practicality of the protocol. The reaction is proposed to procced through an
