ABSTRACT: In the crystal structure of the title compound, C(21)H(15)N(5)O(2), the planar indolone unit and the pyran ring are almost perpendicular to each other [dihedral angle = 89.41?(2)°], and the pyrazole and phenyl rings are oriented at an angle of 25.74?(1)°. The mol-ecular packing is stabilized by inter- and intra-molecular C-H?O, N-H?O and C-H?? hydrogen bonds.

6-Amino-1-benzyl-4-(4-chloro-phen-yl)-3-(4-pyrid-yl)-1,4-dihydro-pyrano[2,3-c]pyrazole-5-carbonitrile.

Project description:The crystal structure of the title compound, C(25)H(18)ClN(5)O, was determined in the course of our studies on the synthesis of 1,4-dihydro-pyrano[2,3-c]pyrazole as an inhibitor of the p38 mitogen-activated protein kinase (MAPK). The compound was prepared via a base-catalysed synthesis from 1-benzyl-3-(4-pyrid-yl)-1H-pyrazol-5(4H)-one with p-chloro-aldehyde and malononitrile. The crystal data obtained were used to generate a three-dimensional pharmacophore model for in silico database screening. The phenyl ring is disordered over two positions, with site occupancy factors of 0.55 and 0.45. The dihedral angles between the 1,4-dihydropyrano[2,3-c]pyrazole unit and the chloro-phenyl and pyridine rings are 83.7 (1) and 16.0 (1)°, respectively. The chloro-phenyl and pyridine rings make a dihedral angle of 86.8 (2)°.

3,4-Dimethyl-pyrano[2,3-c]pyrazol-6(2H)-one.

Project description:The asymmetric unit of the title compound, C(8)H(8)N(2)O(2), comprises two independent mol-ecules in both of which, all non-H atoms lie in a common plane (r.m.s. deviation = 0.014 and 0.017?Å). In the crystal, N-H?O hydrogen bonds connect the mol-ecules into zigzag chains running along [10-1]. Weak C-H?O inter-actions connect the chains into an infinite network.

6-Amino-3-methyl-4-(3-nitro-phen-yl)-1-phenyl-1H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile.

Project description:The title compound, C(20)H(15)N(5)O(3), was synthesized by the one-pot reaction of a four-component reaction protocol in aqueous medium. The pyrano[2,3-c]pyrazole system is essentially planar, with a maximum deviation of 0.026?(2)?Å. The 3-nitro-phenyl and phenyl rings make dihedral angles of 81.11?(5) and 13.36?(1)°, respectively, with the mean plane of the pyrano[2,3-c]pyrazole ring. The crystal structure is stabilized by N-H?N hydrogen bonds, which form infinite chain propagating along the c axis and by N-H?O hydrogen bonds, which form infinite chains propagating along the a axis. There are also N-O?N-C dipole-dipole inter-actions along the a axis with an O?N distance of 3.061?(3)?Å, which is shorter than that of the N-H?O hydrogen bond [3.196?(3)?Å].

2,3-Dihydro-1H-pyrrolo-[1,2-a]indole-9-carbonitrile.

Project description:The asymmetric unit of the title compound, C12H10N2, which may serve as a model for mitosenes, contains two independent mol-ecules. The conformation of the five-membered rings in both molecules is envelope, with the central CH2-CH2-CH2 C atom at the flap in each case.

2-Oxo-4-phenyl-1,2,5,6-tetra-hydro-benzo[h]quinoline-3-carbonitrile.

Project description:In the mol-ecule of the title compound, C(20)H(14)N(2)O, the tetra-hydro-benzo[h]quinoline fused-ring system is buckled owing to the ethyl-ene -CH(2)CH(2)- fragment, the benzene ring and the pyridine ring being twisted by 19.7?(1)°. The 4-substituted aromatic ring is bent away from the pyridine ring by 62.9?(1)° in order to avoid crowding the cyanide substituent. In the crystal, two mol-ecules are linked by a pair of N-H?O hydrogen bonds to form a centrosymmetric dimer.

2-Amino-7-oxo-4,5,6,7-tetra-hydro-1-benzothio-phene-3-carbonitrile.

Project description:In the title compound, C(9)H(8)N(2)OS, the benzothio-phene ring is substituted with amino, oxo and carbonitrile groups. The thio-phene ring is essentially planar (r.m.s. deviation = 0.0003 Å), while the cyclo-hexene ring is in a half-chair conformation. In the crystal, N-H⋯O hydrogen bonds generate chains of mol-ecules in a zigzag pattern along the b axis. Pairs of N-H⋯N hydrogen bonds form centrosymmetric head-to-head dimers about inversion centres, corresponding to an R(2) (2)(12) graph-set motif. In addition, rather weak N-H⋯S inter-actions are also present in the structure and the supra-molecular assembly is further consolidated by π-π stacking inter-actions between the benzothio-phene rings, disposed at a distance of 3.742 (3) Å.
