Chemoselective Cu-catalyzed synthesis of diverse <i>N</i>-arylindole carboxamides, β-oxo amides and <i>N</i>-arylindole-3-carbonitriles using diaryliodonium salts
Chemoselective copper-catalyzed synthesis of diverse N-arylindole-3-carboxamides, β-oxo amides and N-arylindole-3-carbonitriles from readily accessible indole-3-carbonitriles, α-cyano ketones and diaryliodonium salts has been developed. Diverse N-arylindole-3-carboxamides and β-oxo amides were successfully achieved in high yields under copper-catalyzed neutral reaction conditions, and the addition
