Copper-Catalyzed Cross Dehydrogenative Coupling Reactions of Tertiary Amines with Ketones or Indoles
摘要:
A novel cross dehydrogenative coupling (CDC) reaction of N,N-dimethylanilines with methyl ketones by cooperative copper and aminocatalysis has been developed, which leads to the formation of beta-arylamino ketones in 42-73% yields. Moreover, the copper-catalyzed alkylation of free (NH) indoles with N,N-dimethylanilines via CDC reaction is also presented, affording alkylated indoles in 52-78% yields.

materials, and there has been a growing interest in new synthetic methods for their preparation. In this paper, we report a direct cross-coupling reaction of heteroarenes with N,N-dimethylanilines in the presence of copper catalyst. Oxygen and/or air are successfully used as the oxidant, which is of great importance to the industrialized economies. The reaction is compatible with a wide range of heterocycles
