(4-Chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone
The title compound, C(18)H(13)ClO(3), has an intra-molecular O-H⋯O=C hydrogen bond between the carbonyl group and the hydr-oxy substituent on the naphthalene ring system. The angle between the C=O bond plane and the naphthalene ring system is relatively small [20.96 (8)°]. The angle between the benzene ring and the carbonyl group is rather large [35.65 (9)°] compared to that in an analogous com...
متن کاملSynthesis and antibacterial activities of novel 4-hydroxy-7-hydroxy- and 3-carboxycoumarin derivatives.
Coumarin derivatives are used as fluorescent dyes and medicines. They also have some notable physiological effects, including the acute hepatoxicity and carcinogenicity of certain aflatoxins, the anticoagulant action of dicoumarol, and the antibiotic activity of novobicin and coumerymycin A1. Because the number of drug resistant strains is increasing at present, the synthesis of new antibacteri...
متن کاملN-(4-Fluorobenzoyl)-2-hydroxy-4-methylbenzohydrazide
In the title compound, C(15)H(13)FN(2)O(3), the aromatic rings are aligned at an angle of 10.15 (3)°. The mol-ecules are packed with π-π stacking inter-actions [mean inter-planar distances of 3.339 (2) and 3.357 (3) Å] and the crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. An intramolecular N-H⋯O interaction also occurs.
متن کامل4-Hydroxy-2,2,6,6-tetramethylpiperidinium trifluoroacetate
The title compound, C(9)H(20)NO(+)·C(2)F(3)O(2) (-), is an important inter-mediate in the synthesis of hindered light stabilizers. The piperidinium ring adopts a chair conformation with the hydroxyl group in an equatorial position. The crystal packing is stabilized by O-H⋯O and N-H⋯O hydrogen bonds. The CF(3) group is disordered over two positions with almost equal site occupancy factors.
