and efficient method for the synthesis of 2-oxo-acetamidines via copper-catalyzed oxidative cross-coupling of amines with α-amino ketone compounds was achieved. In this reaction, the C − N bond of α-amino ketone is broken and new C − N and CN bonds are constructed in one single transformation. This reaction system has a broad substrate scope and provides a facile pathway for the synthesis of 2-oxo-acetamidines
A general and mild method for the construction of a carbon–nitrogen bond via copper-catalyzedoxidativecross-coupling of amines with α-aminocarbonyl compounds was achieved. Amines, either aliphatic primary amines, aromatic primary amines or secondary amines can be used as the starting materials. When R2 was different from R3, two isomers would be observed. Therefore, this reaction system has a broad
