Benzo-γ-pyrones. Part XV. Conversion of some 4-Oxo-4H-1-benzopyran-2-carboxylic Acids into 4H-1-Benzopyran-4-ones via Isoxazoles

The preparation of 5-substituted-3-isoxazolecarboxylic acids 2a-c and their transformation into the corresponding 2-aminochromones (5a-c) and 3-cyano-2-methylchromones (6a-c) is described. The structures of oximes of methylchromones were revised to isoxazoles 2d-f. The structures of the obtained compounds were proved by spectral methods (1H, 13C NMR, IR and MS). Key words: chromones, isoxazoles, NMR and MS spectra
