چکیده
The title mol-ecule, C(22)H(17)BrN(2)O(4)S, has a twisted U shape, the dihedral angle between the quinazolin-4-one and bromo-benzene ring systems being 46.25 (8)°. In order to avoid steric clashes with adjacent substituents on the quinazolin-4-one ring, the N-bound tolyl group occupies an orthogonal position [dihedral angle = 89.59 (8)°]. In the crystal, mol-ecules are connected into a three-dimensional architecture by C-H⋯O inter-actions, with the ketone O atom accepting two such bonds and a sulfonate O atom one.

In the title quinazolin-4-one derivative, C(24)H(20)N(2)O(3), both the 4-methyl-benzoate [dihedral angle = 83.90 (9)°] and 2-tolyl [87.88 (9)°] groups are almost orthogonal to the central fused ring system. These aryl groups are oriented towards the quinazolin-4-one-bound methyl group. In the crystal, mol-ecules are connected into a three-dimensional architecture by C-H⋯O, C-H⋯π and π-π [ring c...

In the title compound, C(21)H(16)N(2)O(3)S, the central quinazolin-4-one ring is planar (r.m.s. deviation = 0.037 Å). The N-bound benzene and thio-phenyl rings are almost perpendicular to the central plane [dihedral angles = 82.22 (5) and 77.05 (13)°, respectively]. Mol-ecules are connected into a three-dimensional array by C-H⋯O inter-actions involving both carbonyl O atoms. The thio-phene rin...

In the title compound, C(23)H(17)ClN(2)O(3), the quinazoline fused-ring system, including the ring-bound carbonyl-O and methyl-C atoms, is close to being planar (r.m.s. deviation = 0.044 Å) and is essentially orthogonal to both the 2-tolyl ring [dihedral angle = 89.51 (8)°] and to the ester group [the C-O-C-C torsion angle = -103.69 (16)°]. The carboxyl-ate group is almost coplanar with the ben...
متن کاملSynthesis, anti-inflammatory and analgesic evaluation of thioxoquinazolinone derivatives.
A series of 3-substituted-2-thioxoquinazolin-4(3H)-one derivatives have been synthesized and their structures have been elucidated on the basis of IR, (1)H-NMR, elemental analysis and mass spectroscopic studies. Anti-inflammatory and analgesic activity of the synthesized compounds was evaluated by Carrageenan induced rat paw edema method and Eddy's hot plate method respectively. Among the synth...
