Chemo- and Regioselective Catalyst-Controlled Carbocyclization of Alkynyl Ketones: Rapid Synthesis of 1-Indanones and 1-Naphthols. 
A catalyst-controlled intramolecular carbocyclization of 2-alkynyl aryl ketones is presented.  Under rhodium(III) catalysis, 1-indanones are formed through 5-exo-dig carbocyclizations with exclusive chemo-, regio- and stereoselectivity.  When catalyzed by copper(I), 1-naphthols are obtained through 6-endo-dig carbocyclizations with exclusive chemo- and regioselectivity.
