A copper(II)-catalyzed oxidative reaction for the one-pot simultaneous synthesis of quinolines and gem-diamine derivatives from N-arylglycine ethyl esters and enamides is described. In this reaction, the two fragments in an enamide substrate react with th

A simple and highly efficient cross-dehydrogenative-coupling (CDC) reaction between N -aryl glycine esters and imides or amides by the catalysis of a copper salt without the requirement of peroxide agents is described. The novel reaction provides a facile approach for the synthesis of α-substituted α-amino acid esters through C-H/N-H oxidative cross-coupling. A possible mechanism for the CDC reaction by using copper as a catalyst and air as the terminal oxidant is also proposed. This synthetic approach has the advantages of good yields, simple operation and mild reaction conditions.
