2-Aryl indoles could be prepared in excellent yields via the intramolecular cyclization of ο-alkynyl N,N-dialkylanilines. The reaction is efficiently promoted by the catalytic amount of KOt-Bu in DMSO at room temperature. A reaction mechanism involving α-aminoalkyl radical intermediates is suggested.
