AbstractWe have developed a simple and efficient copper‐catalyzed method for the synthesis of 2‐amino‐1H‐indole‐3‐carboxylate derivatives via cascade reactions of substituted N‐(2‐halophenyl)‐2,2,2‐trifluoroacetamide with alkyl 2‐cyanoacetate or malononitrile under mild conditions, and the method is of wide practical application.
