In the title compound, C12H12N2O2, synthesized by ammonolysis of 3-phenyl-isoxazole-5-carbonyl chloride in di-chloro-methane, the dihedral angle between the isoxazole ring and the phenyl ring is 14.05 (7)°. In the crystal, centrosym-metrically related mol-ecules are linked into dimers by pairs of C-H⋯O hydrogen bonds, generating rings of graph-set motif R 2 (2)(10).

In the structure of the title compound, C(12)H(11)N(3)O(3)·H(2)O, the dihedral angle formed by the benzene and isoxazole rings is 2.03 (8)°. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. In the crystal structure, mol-ecules are linked into a three-dimesional network by inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, and by π-π stacking inter-actions...

α-Enone 1, reacts with hydrazines, hydroxylamine hydrochloride, thiourea, diethylmalonate, malononitrile ethyl cyanoacetate to give the corresponding indazole, oxime, isoxazole, quinazoline, chromene and quinoline derivatives. The structures of all the synthesized compounds were confirmed by micro analytical and spectral data. The antimicrobial and the antitumor activities of some of the synthe...

The title compound, C(25)H(23)NO(5), comprising two stereogenic carbon atoms of the same configuration, crystallizes in a centrosymmetric space group as a racemate. The six-membered pyran ring and the five-membered isoxazole ring adopt sofa and twisted conformations, respectively. The dihedral angle between the benzene ring and the mean plane through the near coplanar atoms of the pyran ring is...
