CuI-catalyzed intramolecular cyclization of 3-(2-aminophenyl)-2-bromoacrylate: synthesis of 2-carboxyindoles
Abstract A new approach was described for the synthesis of substituted 2-carboxyindole using 3-(2-aminophenyl)-2-bromo-acrylates through a CuI-catalyzed intramolecular coupling. The reactions were mild, rapid and with good to excellent yields.
