Ring fused quinoline heterocycles such as isoxazolo-, pyrrolo- and pyrazoloquinolines (7,9,11,14) have been prepared by intramolecular 1,3-dipolar cycloaddition reactions starting from the suitable intermediates. The structures of the products were assigned by means of analytical and spectroscopic data.
