A rhodium-catalyzed oxidative C2-alkenylation of indoles containing a N-(p-tolyl)carboxamide group with substituted alkynes via C-C bond formation and subsequent C-N bond cleavage has been described. This protocol represents direct access to C2-alkenylated free (NH)-indoles, which are important building blocks in the synthesis of natural and pharmacological compounds. (C) 2014 Elsevier Ltd.
