3-(4-Fluorophenyl)-2-(4-methoxyphenoxy)-4-oxo-5-phenyl-4,5-dihydro-3H-pyrrolo[3,2-d]pyrimidine-7-carbonitrile
There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(26)H(17)FN(4)O(3), which differ in the dihedral angles between the aromatic rings (fluorophenyl, phenyl) and the pyrrolopyrimidine rings [0.6 (3)/76.3° and 73.7 (3)/64.6°, respectively]. The crystal structure is mainly stabilized by C-H⋯O and C-H⋯F inter-actions.

In the title compound, C(21)H(16)N(4)O(2), the dihedral angle between the meth-oxy-substituted benzene ring and the ring system formed by the pyridinone ring and the pyrazole ring is 57.4 (1)°, and that between the unsubstituted phenyl ring and the ring system is 135.6 (1)°. In the crystal structure, mol-ecules are linked together via inter-molecular N-H⋯O hydrogen bonds.

The title compound, C(21)H(21)N(3)O, was obtained by cyclo-condensation of 3-amino-5-methyl-[1,1'-biphen-yl]-2,4-di-car-bo-nitrile with cyclo-hexa-none. The six-membered 1,3-diaza ring assumes an envelope conformation [with the flap atom displaced by 0.511 (7) Å from the plane through the other ring atoms] and the cyclo-hexane ring displays a chair conformation. The dihedral angle between the a...
متن کامل3-(4-Fluorophenyl)-2-(2-naphthyloxy)-4-oxo-5-phenyl-4,5-dihydro-3H-pyrrolo[3,2-d]pyrimidine-7-carbonitrile
The title compound, C(29)H(17)FN(4)O(2), may be used as a new precursor for obtaining bioactive mol-ecules. There are two crystallographically independent mol-ecules in the asymmetric unit. The phenyl ring, 4-fluoro-phenyl ring and 2-naphth-yloxy ring are twisted with respect to the pyrrolopyrimidine ring by 52.30 (11)/49.05 (11), 80.94 (10)/88.36 (10) and 60.58 (7)/83.76 (7)°, respectively. Th...
متن کامل3-Oxo-5-(piperidin-1-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile
In the title compound, C(9)H(12)N(4)O, the piperidine ring adopts a chair conformation and makes a dihedral angle of 42.49 (11)° with the approximately planar pyrazole moiety [maximum deviation = 0.038 (2) Å]. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds and a weak C-H⋯O inter-action link the mol-ecules into sheets lying parallel to (110).
