Abstract

Oxa-, thia- and imidazolones are reactive inputs as electron-rich olefin components in Povarov reactions. On interaction with anilines and aldehydes, these substrates afford the corresponding multicomponent adducts in a regioselective manner. Intramolecular processes are also explored. Post-condensation oxidation provides convenient access to a variety of fused quinoline derivatives.
