Bismuth(III) triflate [Bi(OTf)(3)] has been developed as an efficient and mild catalyst for intramolecular Friedel-Crafts cyclizations of tertiary alcohols to prepare disubstituted tetrahydronapthalenes, chromans, thiochromans, tetrahydroquinolines, and tetrahydroiso-quinolines. The method represents a unified strategy to synthesize a variety of ring systems from tertiary alcohols using a common Lewis acid. (C) 2013 Elsevier Ltd. All rights reserved.
