چکیده
The asymmetric unit of the title compound, C(22)H(18)N(2)O(2), contains two independent mol-ecules, which differ in the orientations of the benzyl groups with respect to the planar (r.m.s. deviations of 0.031 and 0.020 Å) quinazoline-2,4-dione skeletons [dihedral angles of 73.97 (4) and 70.07 (4)° in the first mol-ecule and 75.63 (4) and 63.52 (3)° in the second]. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π interactions and aromatic π-π stacking inter-actions [centroid-centroid distance = 3.735 (2) Å].

The title compound, C19H19N5O5·3.5H2O, crystallizes with 3.5 mol-ecules of water in the asymmetric unit, one of which lies on a mirror plane. One of the water mol-ecules links the mol-ecules, forming centrosymmetric dimers. These dimers are then linked through further N-H⋯O and O-H⋯O hydrogen bonding, leading to the observed three-dimensional structure.

4-Benzyl-1,2,4-triazin-3,5(2H,4H)-dione (3-benzyl-6-azauracil, 2), and 2,4-dibenzyl-1,2,4-triazin-3,5(2H,4H)-dione (1,3-dibenzyl-6-azauracil, 3) were synthesized by the reaction of 1,2,4-triazin-3,5(2H,4H)-dione (6-azauracil, 1) with benzyl bromide and potassium carbonate in dry acetone via the 18-crown-6-ether catalysis. In these reaction methods, we developed more convenient and efficient met...
متن کاملSynthesis and activity of 1,3,5-triphenylimidazolidine-2,4-diones and 1,3,5-triphenyl-2-thioxoimidazolidin-4-ones: characterization of new CB1 cannabinoid receptor inverse agonists/antagonists.
Obesity and metabolic syndrome, along with drug dependence (nicotine, alcohol, opiates), are two of the major therapeutic applications for CB(1) cannabinoid receptor antagonists and inverse agonists. In the present study, we report the synthesis and structure-affinity relationships of 1,5-diphenylimidazolidine-2,4-dione and 1,3,5-triphenylimidazolidine-2,4-dione derivatives. These new 1,3,5-tri...

In the title compound, C(20)H(20)N(2)O(3), the ten atoms comprising the quinazoline ring are essentially planar (r.m.s. deviation = 0.024 Å), and this plane is almost orthogonal to the terminal phenyl ring [dihedral angle = 82.87 (7)°]. The conformation about the ethyl-ene bond [1.335 (2) Å] is E and there is a significant twist between this residue and the adjacent phenyl ring [C-C-C- torsion ...

In the title compound, C(19)H(17)ClN(2)O(3), the conformation about the ethyl-ene bond [1.333 (2) Å] is E. The ten atoms comprising the quinazoline ring are essentially planar (r.m.s. deviation = 0.032 Å) and their mean plane forms a dihedral angle of 13.89 (7)° with the terminal phenyl ring; the mol-ecule has an open conformation as these substituents are directed away from each other. In the ...
