In the title compound, C25H23NO4, the pyran ring of the chroman moiety has an envelope conformation with the methyl-ene C atom as the flap. The isoxazole ring has a twist conformation on the O-C bond. The dihedral angle between their mean planes is 57.87 (9)°. The attached phenyl and benzene rings are twisted away from its mean plane by 56.19 (10) and 50.57 (10)°, respectively. These two rings ...

4-Aminoantipyrine was utilized as key intermediate for the synthesis of pyrazolone derivatives bearing biologically active moieties. The newly synthesized compounds were characterized by IR, 1H- and 13C-NMR spectral and microanalytical studies. The compounds were screened as anticancer agents against a human tumor breast cancer cell line MCF7, and the results showed that (Z)-4-((3-amino-5-imino...

Indole-3-carbaldehyde and chloro ethyl acetate were dissolved in DMF. To this reaction mixture anhydrous ...

The title compound, 5-(1H-indol-3-yl)-1-methyl-3-phenyl-1,6-benzodiazocin-2(1H)-one, was synthesized for the first time by a one-step, two-component reaction between 1-methylbenzimidazole and benzoylindolyl-3-acetylene. product characterized 1H-NMR, 13C-NMR, IR spectroscopy HRMS.

In the mol-ecule of the title compound, C(10)H(12)N(2), the six- and five-membered rings are almost co-planar, forming a dihedral angle of 3.56 (8)°. In the crystal structure, neighbouring mol-ecules are linked together by inter-molecular N-H⋯N hydrogen bonds into one-dimensional infinite chains along the c axis. The crystal structure, is further stabilized by weak inter-molecular C-H⋯π and π-π...
