4-Substituted pyridines linked to iodoarene groups with alkyl amide tethers can be converted to the corresponding alkylidene dihydropyridines by treatment with ethyl chloroformate and Et3N. Subsequent exposure to Pd-catalyzed Mizoroki–Heck reaction conditions results in efficient intramolecular cyclization at the exocyclic alkene to afford isoindolinone and oxindole derivatives.
