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. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.
