We report herein the synthesis of isoquinolines through a copper(I)-catalyzed domino reaction. During this transformation, three molecules of terminal alkynes, 2-bromoaryl aldehydes (ketones), and acetamide react together, in a sequence including Sonogashira coupling, condensation, 6-endo-dig cyclization, elimination of acetic acid, and hydrolysis. In this reaction, isoquinolines with broad functional
