Reactions of [(η(6)-cymene)Ru(μ-Cl)Cl]2 with acylpyrazolone ligands HQ' (HQ' in general; in detail, HQ(CH2Cl) = 2-chloro-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone), HQ(hex) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)heptan-1-one), HQ(nPe) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3,3-dimethylbutan-1-one)), in the presence of base, gave the corresponding [(η(6)-cymene...
The novel racemic secondary alcohol (±)-2-{[4-(4-bromophenyl)-5-phenyl-4H-1,2,4-triazol-3-yl]sulfanyl}-1-phenyl-1-ethanol (12) has been successfully synthesized through S-alkylation of 4-(4-bromophenyl)-5-phenyl-4H-1,2,4-triazole-3-thiol (10) in alkaline medium with 2-bromo-1-phenylethanone followed by reduction the corresponding ketone 11. All compounds were characterized IR, 1D (1H, 13C, DEPT...
This study aimed to synthesize quinolinone derivatives and investigate their cytotoxic activity. The compound 1-azacoumarin-3-carboxylic acid (2-oxo-1H-quinoline-3-carboxylic acid) was obtained via the cyclocondensation of 2-hydroxybenzaldehyde with diethyl malonate in base catalyst give ethyl coumarin-3-carboxylate, followed by ammonolysis ester (ethyl coumarin-3-carboxylate) ammonia presence ...
In the title compound, C(18)H(16)O(4)S, the 4-hydroxy-phenyl ring is rotated out of the benzofuran plane, making a dihedral angle of 34.52 (6)°. The methyl group of the methyl-sulfanyl substituent is almost perpendicular to the plane of the benzofuran fragment [100.90 (8)°] and is slightly tilted towards it. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds, and by int...
