A Pd‐catalyzed spirocyclization involving a sequential carbopalladation, intramolecular C−H activation, and a highly regioselective alkyne insertion to afford spirooxindoles and spirodihydrobenzofurans has been achieved. The spirocyclic products were generated in good to excellent yields with complete regiocontrol in a readily scalable procedure.
