The rapid synthesis of the isoindolinone skeleton has been accomplished by a palladium-catalyzed one-pot tandem process, which consists of an isocyanideinsertion/hydration (carboxamidation) and 5-exo-dig cycloisomerization (hydroamidation) reaction sequence that afforded the products in good to excellent yields. Preliminary mechanistic studies of this sequential C–C/C–O/C–N bond formation process
