iles and 2-aminoindole-3-carboxylates by the reaction of N-(2-iodophenyl)formamides with malononitrile and cyanoacetates, respectively, in the presence of a catalytic amount of copper(I) iodide using potassium carbonate as a base is reported. 2-aminoindole-3-carboxylates - 2-aminoindole-3-carbonitriles - N-(2-iodophenyl)formamides - copper(I) iodide - coupling
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.

N-heterocyclic carbene (NHC)-catalyzed enantioselective [3 + 3] annulation of 2-bromoenals with 2-amino-1H-indoles has been developed. A series of functionalized 2-aryl-2,3-dihydropyrimido[1,2-a]indol-4(1H)-ones were synthesized using NHCs as the catalyst in good yields with high to excellent enantioselectivities.
