                                A facile synthesis of a series of 1-alkoxyisoguinolines and (2H)-isoguinolones by an intramolecular 6-endo-dig cyclization of ortho-alkynylbenzonitriles in the presence of a catalytic amount of hydrido(dimethylphosphinous acid-kappa P)[hydrogen bis(dimethylphosphinito-kappa P)]platinum(II) in various alcohols at 65-90 degrees C is described for the first time.
