Various pyrazolo[1,5‐ a ]quinolines were synthesized via the intramolecular Friedel‐Crafts reaction of 1‐aryl‐5‐styrylpyrazoles and the following base‐catalyzed aerobic oxidation process. The required 1‐aryl‐5‐styrylpyrazoles were readily prepared from the corresponding conjugated dienones and arylhydrazines in a one‐pot process.
