Conversion of tetrahydroimidazo[1,2- b ]isoxazoles into derivatives of 2H-imidazole, 1-hydroxypyrrole, and 4-oxotetrahydropyridine [Elektronische Daten] [L. Grigor'eva, A. Tikhonov, V. Martin, L. Volodarskii] Reaction of 1,2-hydroxylaminooximes with acetylacetone gives tetrahydroimidazo[1,2-b]isoxazoles. 4-Phenyltetrahydroimidazo[1,2-b]isoxazole in methanolic HCl forms the corresponding 2-acetonyl-2H-imidazole. Both tetrahydroimidazo[1,2-b]isoxazoles and 2-acetonyl-2H-imidazole on heating in aqueous KOH convert into 4-oxo-1,2,3,4-tetrahydropyridines along with 3-acetyl-1-hydroxypyrroles.
