The conversion of the 2(3 H )‐furanone into the oxazinone and pyrimidinone derivatives is studied. A 2‐(furan‐2‐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.
