ACCESS TO CONVENIENT SYNTHESIS OF OXAZINONE AND PYRIMIDINONE HETEROCYCLES DERIVED FROM 2(3H)-FURANONE

摘要

The conversion of the 2(3 H )-furanone into the oxazinone and pyrimidinone derivatives is studied. A 2-(furan-3-ylmethylene)-4-oxo-4-phenylbutanoyl azide 3 was synthesized to carry out these conversions through its thermolysis in dry benzene and/or base-catalyzed decomposition of this azide in the presence of different amines. The structures of all compounds were demonstrated from their spectral data and elemental analyses.
