Synthesis and Biological Evaluation of 4-hydroxychromenyl arylmethyl-6-hydroxy pyrimidine-2, 4-dione Derivatives
Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed ...
متن کامل3,4-Bis[4-(4-methoxyphenoxy)phenyl]-2,5-dihydrofuran-2,5-dione
In the crystal structure of the title compound, C(30)H(22)O(7), neighbouring benzene rings are twisted out of the plane of the five-membered ring by 27.30 (3) and 45.47 (3)°.
متن کامل4-(4-Methoxyphenyl)-1-phenylpyridine-2,6(1H,3H)-dione
In the title compound, C(18)H(15)NO(3), the pyridine-2,6-dione ring adopts an envelope conformation. The phenyl ring lies approximately perpendicular to the mean plane of the pyridine-2,6-dione ring [dihedral angle = 81.5 (1)°], while the methoxy-phenyl ring is tilted to the same plane by a dihedral angle of 34.8 (1)°. Inter-molecular C-H⋯O inter-actions link the mol-ecules into chains along [1...
متن کامل4-[(Hydroxy)(4-methylphenyl)methylidene]isochroman-1,3-dione
In the title compound, C(17)H(12)O(4), the six-membered heterocyclic ring adopts a distorted screw-boat conformation. The mol-ecular structure exhibits an S(6) ring motif, owing to an intra-molecular O-H⋯O hydrogen bond. In the crystal, weak C-H⋯O contacts generate an infinite chain along the c axis. There are also π-π stacking inter-actions between neighbouring isochromanedione benzene rings, ...
متن کامل1-(4-Chlorophenylsulfonyl)-5-(4-fluorophenyl)-5-methylimidazolidine-2,4-dione
The title compound, C(16)H(12)ClFN(2)O(4)S, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules are U-shaped with similar geometries and conformations. The mean planes through the benzene rings are inclined to one another by 6.07 (8)° in mol-ecule A and 8.67 (8)° in mol-ecule B. They are separated with a centroid-centroid distance of 3.9096 (10) Å i...
