Abstract


The conversion of the 2(3H)-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.
