2-Amino-5-oxo-4-phenyl-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile
In the title mol-ecule, C(16)H(14)N(2)O(2), the fused cyclo-hexene and pyran rings adopt an envelope and a flattened boat conformation, respectively. In the crystal, N-H⋯N and N-H⋯O hydrogen bonds link the mol-ecules into corrugated sheets parallel to the bc plane.
متن کامل3-(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.
متن کامل5′-Methyl-4′-oxo-7′-phenyl-3′,4′-dihydro-1′H-spiro[cyclohexane-1,2′-quinazoline]-8′-carbonitrile
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 کاملMethyl 2-{[(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-ylidene)(4-nitrophenyl)methyl]amino}-3-phenylpropanoate
The mol-ecule of the title compound, C(27)H(24)N(4)O(5), exists in the keto-enamine tautomeric form, stabilized by an intra-molecular N-H⋯O hydrogen bond. An intra-molecular C-H⋯·O hydrogen bond also occurs. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into chains.
متن کامل2-Oxo-4-phenyl-1,2,5,6-tetrahydrobenzo[h]quinoline-3-carbonitrile
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 ...
