Article abstract of DOI:10.1016/S0040-4020(01)91189-5

Chromone and 2-hydroxychromanone react with hydroxylamine to give several products through attack at Ca2.The aldoxime 2 is transformed to dioxime 4 or to isoxazole 3.The dioxime exists as a tautomer mixture; it reacts in several ways, giving chromoneoxime
