An efficient microwave assisted one-pot synthesis of substituted 3-(phenylmethylene)isoindolin-1-ones is reported via a copper-free Sonogashira coupling and a regioselective 5-exo-dig cycloisomerization. This domino reaction was also extended to other related heterocycles. (C) 2011 Elsevier Ltd. All rights reserved.
