6,7,8,9,10,11-Hexahydro-13H-azocino[2,1-b]quinazolin-13-one
The title compound, C(14)H(16)N(2)O, is a synthetic analogue of quinazolone alkaloids with pyrrilo, pyrido and azopino rings. The quinazolinic part of the mol-ecule is generally planar within 0.037 (3) Å; the eight-membered ring exhibits an inter-mediate conformation between the chair and boat forms as it is typical for cyclo-octene rings. An ethyl-ene group of the azopino ring is disordered ov...
متن کامل4,7,8-Trimethyl-2H-chromen-2-one
The mol-ecule of the title compound, C(12)H(12)O(2), is essentially planar, with a maximum deviation from the mean plane of all non-H atoms of 0.038 (1) Å for the methyl C atom in the 8-position. The crystal structure is characterized by anti-parallel π-π stacking along the c axis, with centroid-centroid distances as short as 3.866 (1) Å. In the crystal, C-H⋯O hydrogen bonds connect the mol-ecu...
متن کامل2,2,7-Trimethyl-2,3-dihydroquinazolin-4(1H)-one
There are two independent mol-ecules in the the asymmetric unit of the title compound, C(11)H(14)N(2)O. The heterocyclic ring of the bicyclic system has a sofa conformation, with the C atom bearing the two methyl groups displaced by 0.541 (7) Å from the rest of the atoms of the ring [planar to within 0.064 (9) Å]. Mol-ecules are linked into centrosymmetric dimers via N-H⋯O hydrogen bonds.
متن کامل2,2,9-Trimethyl-2,3-dihydropyrano[2,3-a]carbazol-4-(11H)-one
The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-7-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. The mol-ecules contain an essentially planar 6-methyl-indole unit. The second aromatic ring is significantly bent away from the plane of this unit, with maximum deviations of 0.171 (1) and 0.185 (1) Å for two of the C atoms. I...
متن کامل5-(4-Fluorophenyl)-2,2,6-trimethyl-4H-1,3-dioxin-4-one
The 1,3-dioxine ring in the title compound, C(13)H(13)FO(3), is in a half-boat conformation with the methyl-bonded C atom 0.612 (2) Å out of the plane defined by the remaining five atoms.
