In the title compound, C17H15ClO3S, the dihedral angle between the mean planes of the benzo-furan and 3-methyl-phenyl rings is 76.99 (4)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds into chains along the b-axis direction. These chains are linked by π-π inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.976 (2) Å].

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...

The aromas of cultivar Meeker red raspberry from Oregon and Washington were analyzed by aroma extract dilution analysis. Seventy-five aromas were identified [some tentatively (superscript T)] by mass spectrometry and gas chromatography-retention index; 53 were common to both, and 22 have not been previously reported in red raspberry. Twenty-one compounds had an equivalent odor impact in both: 2...

In the title compound, C(16)H(19)ClO(2)S, the cyclo-hexyl ring adopts a chair conformation and the aryl-sulfinyl unit is positioned equatorial relative to the cyclo-hexyl group. The least-squares plane through all six C atoms of the cyclo-hexyl ring makes a dihedral angle of 74.80 (6)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked through inter-molecular ...

The title compound, C(16)H(13)IO(3)S, was prepared by the oxidation of 5-iodo-2,7-dimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 76.31 (8)° with the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic π-π inter-actions between the furan and benzene rings of neighbouring mol-ecules, and between th...
