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 کامل(4R,7S)-2-Amino-4-(3,4-dimethoxyphenyl)-5-oxo-7-phenyl-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile monohydrate
The title compound, C(24)H(22)N(2)O(4)·H(2)O, was obtained by the reaction of 3,4-dimeth-oxy-benzaldehyde, malononitrile and 5-phenyl-cyclo-hexane-1,3-dione. The cyclo-hexyl and pyran rings show half-boat and V-shaped conformations, respectively. The dihedral angle between the phenyl and benzene ring planes is 30.67 (9)°. The organic mol-ecules are packed in a two-dimensional network parallel t...

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...

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 ...

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.
