8-Methyl-4-phenyl-2,3,3a,4,5,9b-hexahydrofuro[3,2-c]quinoline
The title compound, C(18)H(19)NO, was synthesized from the multi-component one-pot reaction between p-toluidine, benzaldehyde and 2,3-dihydro-furan in the presence of palladium dichloride. There are two mol-ecules in the asymmetric unit. The crystal packing is stabilized by classical inter-molecular N-H⋯O hydrogen bonds.
متن کامل2-Methyl-4-phenyl-3,4-dihydroquinazoline
The title compound, C(15)H(14)N(2), was formed during the lithia-tion of 2-methyl-quinazoline with phenyl-lithium followed by hydrolysis of the inter-mediate lithium 2-methyl-4-phenyl-4H-quinazolin-3-ide. NMR spectra as well as single-crystal X-ray structural data indicate that the reaction product to have the same structure in chloro-form solution as in the crystalline state. The phenyl substi...

In the title pyrimidine derivative, C12H16N2OS, the tetra-hydro-pyrimidine ring adopts an envelope conformation with the C atom of the methyl-ene -CH2- group as the flap. In the crystal, N-H⋯O and N-H⋯S hydrogen bonds connect mol-ecules into undulating sheets perpendicular to the a axis.

In the crystal structure of the title compound, C(28)H(21)Cl(2)N, π-π inter-actions link pairs of mol-ecules into centrosymmetric dimers with a distance of 3.756 (3) Å between the centroids of the pyridine rings. Weak inter-molecular C-H⋯Cl hydrogen bonds further link these dimers into chains propagating along [01]. The pyridine ring forms dihedral angles of 21.52 (1) and 55.87 (2)°, respective...
متن کامل3-Methyl-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid
In the title compound, C(17)H(12)O(4), the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166 Å. The attached phenyl ring makes a dihedral angle of 53.2 (1)° with the fused ring system. The packing of the mol-ecules in the crystal structure is governed by C-H⋯O and O-H⋯O hydrogen-bonding inter-actions.
