4-Hydroxy-3-[(4-hydroxy-6-methyl-2-oxo-3,6-dihydro-2H-pyran-3-yl)(3-thienyl)methyl]-6-methyl-3,6-dihydro-2H-pyran-2-one
The asymmetric unit of the title compound, C(17)H(14)O(6)S, contains four crystallographically independent mol-ecules in which the pyran-one units are essentially planar, with maximum deviations of 0.016 (2), 0.019 (2), 0.025 (2), 0.014 (2), 0.020 (2), 0.010 (2), 0.003 (2) and 0.012 (2) Å. One of the thio-phene rings is disordered over two positions, with an occupancy ratio of 0.739 (4):0.261 (...
متن کامل2-Methoxy-3-[(3,4,5-trimethoxyanilino)methylidene]-3,4-dihydro-2H-1-benzopyran-4-one
The title mol-ecule, C(20)H(21)NO(6), adopts a keto-amine tautomeric form. An intra-molecular N-H⋯O hydrogen bond, classified as a resonanse-assisted hydrogen bond, influences the mol-ecular conformation; the two benzene rings form a dihedral angle of 24.6 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains propagating along [001].
متن کاملAnti-anxiety, Anti-depressant and Anti- Cataleptic Activity of 4-hydroxy-3-[2-(3-nitrophenyl)-2, 3-dihydro-1, 5- Benzothiazepin-4-yl]-2h-chromen-2-one
The Present study was aimed to evaluate the therapeutic effectiveness of 1, 5-benzothiazapine derivative in central nervous diseases. 1,5Benzothiazipines are the seven–membered heterocyclic ring systems which are reported for their behavioral activities. In the current research, we have investigated the effect of 1,5-benzothiazine derivative for its anti-anxiety, antidepressant and anti-catalep...
متن کامل(Z)-2-(4-Nitrobenzylidene)-1-benzofuran-3(2H)-one
In the crystal structure of the title compound, C(15)H(9)NO(4), weak C-H⋯O inter-actions generate rings with R(2) (2)(8) motifs. The supra-molecular aggregation is completed by the presence of C-H⋯O and van der Waals inter-actions.
متن کامل4-Bromo-3-hydroxy-3-(4-hydroxy-2-oxo-2H-chromen-3-yl)indolin-2-one
In the mol-ecule of the title compound, C(17)H(10)BrNO(5), the indoline system and the attached coumarin ring are each essentially planar with maximum deviations of 0.074 (2) and 0.062 (2) Å, respectively. The dihedral angle between them is 85.09 (3)°. In the crystal, all heteroatoms (except for the coumarin oxo O atoms) are involved in intra- and inter-molecular hydrogen bonds. An intra-molecu...
