%X A series of 8-substituted 6,7-benzochromanones has been prepared by cyclization of the corresponding 3-(1-X-2-naphthy1oxy)propionic acids (X = CH3, 0CH3, Br, NO2) with polyphosphoric acid. Direct cyclization of the related 3-(1-X-2-naphthyloxy)propionitriles (X = CH3, OCH3, Br, NO2) with sulphuric acid was successful only with X = Br, NO2. An improved synthesis of 1-methoxy-2-naphthol is reported.
