In this study, we developed direct methods for the synthesis of 3-substituted indoles from o-allcynylan-ilines by utilizing a copper-catalyzed tandem intramolecular cyclization/coupling reaction under mild and simple reaction conditions. Our investigation revealed that choice of the aprotic polar solvents and additives such as camphorsulfonic acid is critical in this reaction. (C) 2013 Elsevier Ltd. All rights reserved.
