STUDIES IN CHROMONE DERIVATIVES: CYCLOADDITION REACTIONS OF 4-OXO-4H-1-BENZOPYRAN-3-CARBOXALDEHYDE IMINES WITH BENZONITRILE OXIDE AND NITRILIMINE OF 4-OXO-4H-1-BENZOPYRAN-3-CARBOXALDEHYDE WITH ALKENES

The chromone imines 1 and benzonitrile oxide reacted regiospecifically to yield Δ2-1,2,4 oxadiazolinyl chromones 2 in good yields.Also the preparation of a novel dipole 6 derived from 3-formylchromone and its cycloaddition reactions with a vari

STUDIES ON CHROMONE DERIVATIVES. NOVEL 1,3 DIPOLAR CYCLOADDITIONS OF 4-OXO-1-BENZOPYRAN-3-CARBALDEHYDE IMINES AND IMINE OXIDES

The chromone imines (2) and nitrile imines (4) reacted smoothly to yield the novel 1,2,4-triazolinyl- and triazepinyl-chromones, (6) and (5) respectively.The facile preparation of nitrones of chromones and their selected reactions with a variety of alkenes to obtain isoxazolidinylchromones (12) is also described.
