QUINOLINE FUSED HETEROCYCLES FROM INTRAMOLECULAR CYCLOADDITION REACTIONS (Dedicated to Dr. Albert Padwa on his 75th birthday)

Ring fused quinoline heterocycles such as isoxazolo-, pyrrolo- and pyrazoloquinolines (7,9,1:1,14) 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.
