An efficient one-pot procedure for the regioselective synthesis of (Z)-3-(halomethylene)-isoindolin-1-ones was developed from easily accessible 2-(2,2-dihalovinyl)benzonitriles. From this key intermediate, a variety of isoindolinones containing an enyne moiety were synthesized in good to excellent yields via palladium-catalyzed Sonogashira reaction. The generated enyne-containing isoindolinones could be further manipulated by iodide induced cyclization reaction to afford a versatile synthetic intermediate 5H-pyrrolo[2,1-a]isoindolol-5-one in high yield and could be further elaborated.

(Chemical Equation Presented) A novel and efficient one-pot regioselective elimination-cyclization-Suzuki approach was developed to afford (Z)-3-arylmethyleneisoindolin-1-ones in good to excellent yields from easily accessible o-gem-dihalovinylbenzamides and organoboron reagents.
