4-[2-(Benzyl-sulfan-yl)acet-yl]-3,4-dihydro-quinoxalin-2(1H)-one.

ABSTRACT: In the title compound, C(17)H(16)N(2)O(2)S, the pyrazinone ring is non-planar (r.m.s. deviation = 0.1595?Å), with maximum deviations for the 4-position N atom and the adjacent non-fused-ring C atom of 0.2557?(15) and -0.2118?(16)?Å, respectively. The dihedral angle between the benzyl ring and pyrazinone rings is 30.45?(18)°. Inter-molecular N-H?O hydrogen-bonding inter-actions forms inversion dimers which lead to eight-membered R(2) (2)(8) ring motifs. The dimers are further connected by C-H?O inter-actions.

2-(2-{[4-Oxo-3-(2-phenyl-eth-yl)-3,4-dihydro-quinazolin-2-yl]sulfan-yl}eth-yl)-2,3-dihydro-1H-isoindole-1,3-dione.

Project description:In the title compound, C(26)H(21)N(3)O(3)S, the quinazolinyl group is essentially planar [r.m.s. deviation for the 10 non-H atoms = 0.057?Å]. The isoindoline-1,3-dione group is linked by an SCH(2)CH(2) chain to the pyrimidinyl C atom that lies between the two N atoms. Also, the phenyl group is linked by a CH(2)CH(2) chain at the N atom adjacent to the carbonyl group. This results in a conformation with these substituents lying to either side of the central quinazolinyl unit, with the former being approximately parallel [dihedral angle = 4.93?(7)°], and the phenyl group being inclined [dihedral angle = 71.61?(9)°] to the central quinazolinyl fused-ring system. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by C-H?O inter-actions, involving all three carbonyl-O atoms, and ?-? inter-actions occurring between the pyrimidinyl and isoindole-benzene rings [inter-centroid distance = 3.5330?(13)?Å].

Ethyl 3-(3-oxo-3,4-dihydro-quinoxalin-2-yl)propano-ate.

Project description:In the title compound, C(13)H(14)N(2)O(3), the fused ring system is almost planar (r.m.s. deviation = 0.015?Å). The r.m.s. deviation for all the non-H atoms of the mol-ecule is 0.065Å. In the crystal, N-H?O and C-H?O hydrogen bonds generate polymeric chains along the b axis containing alternating centrsymmetric R(2) (2)(8) and R(2) (2)(20) loops.

4-[3,4-Dimethyl-1-(4-methyl-phen-yl)-5-oxo-4,5-dihydro-1H-pyrazol-4-yl]-3,4-dimethyl-1-(4-methyl-phen-yl)-4,5-dihydro-1H-pyrazol-5-one.

Project description:In the title compound, C(24)H(26)N(4)O(2), the complete mol-ecule is generated by the application of twofold symmetry. The pyrazole ring is approximately planar [r.m.s. deviation = 0.026 Å] and the benzene ring is twisted out of this plane [dihedral angle = 21.94 (7)°]. A twist in the mol-ecule about the central C-C bond [1.566 (3) Å] is also evident [C-C-C-C torsion angle = 44.30 (14)°]. Supra-molecular layers in the bc plane are formed in the crystal packing via C-H⋯O and C-H⋯π inter-actions.

5-Benzoyl-4-(4-fluoro-phen-yl)-3,4-dihydro-pyrimidin-2(1H)-one.

Project description:In the title mol-ecule, C(17)H(13)FN(2)O(2), the 3,4-dihydro-pyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluoro-phenyl substituent) deviating from the plane defined by the remaining five ring atoms by 0.281?(2)?Å. This plane forms dihedral angles of 85.98?(6) and 60.63?(6)° with the 4-fluoro-phenyl and benzoyl-phenyl rings, respectively. The dihedral angle between the 4-fluoro-phenyl group and the benzene ring is 71.78?(6)°. In the crystal, N-H?O hydrogen bonds link mol-ecules into inversion dimers that are further connected by another N-H?O inter-action into a two-dimensional supra-molecular structure parallel to (101).

3-Isopropyl-1-{2-[(1-methyl-1H-tetra-zol-5-yl)sulfan-yl]acet-yl}-2,6-di-phenyl-piperidin-4-one hemihydrate.

Project description:In the title compound, C24H27N5O2S·0.5H2O, the piperidine ring adopts a distorted boat conformation. The phenyl rings subtend dihedral angles of 69.7?(1) and 88.7?(1)° with the best plane through the piperidine moiety. In the crystal, symmetry-related mol-ecules are linked through a network of C-H?O and C-H?N inter-actions, the former connecting them into zigzag chains along the c-axis direction and the latter forming an R (2) 2(4)motif. The dimer formation (C-H?N) and the repetition of symmetry-related molecules (C-H?O) along the b-axis direction stabilize the packing mode. The water mol-ecule is located on a twofold rotation axis.

Project description:In the title compound, C(20)H(20)O(5), the 2,3-dihydro-1H-indene ring system is essentially planar [maximum deviation = 0.010 (1) Å] and is inclined at an angle of 4.09 (4)° with respect to the phenyl ring. The C=C bond has an E configuration. In the crystal, the mol-ecules are linked into chains propagating in [102] via inter-molecular C-H⋯O hydrogen bonds.

(E)-2-[4-(Trifluoro-meth-yl)benzyl-idene]-2,3-dihydro-1H-inden-1-one.

Project description:In the title mol-ecule, C(17)H(11)F(3)O, the indan ring system and the trifluoro-methyl-substituted benzene ring are approximately individually planar and form a dihedral angle of 1.81?(5)° with each other. In the crystal, mol-ecules are linked by pairs of weak bifurcated (C-H)(2)?O hydrogen bonds to form centrosymmetric dimers, generating R(2) (1)(6) and R(2) (2)(10) ring motifs. These dimers are connected by further weak C-H?O hydrogen bonds into one-dimensional chains along the b axis. Weak C-H?? inter-actions are also present.
