2-(N-Alkenyl-N-aryl)aminochromone-3-carbaldehyde undergoes intramolecular Povarov reaction with aromatic amines in the presence of Ph3P· HClO4 to produce chromenonaphthyridine. The effects of substituent and catalyst have been studie

Figure represented. Regio- and stereoselective syntheses of tetracyclic compounds having chromone, pyrrolidine, and piperidine rings have been accomplished by an intramolecular [3+2] cycloaddition reaction involving azomethine ylide. The reactions were ca
Pericyclic transformations at the periphery of chromen-4-one (=4H-1-benzopyran-4-one): An unusual preference for a 1,5-shift of allylic moieties over the ene reaction

, p. 169 - 180 (2007/10/03)
Quite unlike the reported facile ene reactions on the periphery of many related heterocyclic systems, similarly disposed moieties on the periphery of the chromen-4-one (=4H-1-benzopyran-4-one) system fail to undergo an ene reaction and display a rather un
