11-Methyl-2,3-benzodipyrrin-1-one.
The title compound {alternative names: 11-methyl-2,3-benzopyrromethenone and 3-[(1-methylpyrrol-2-yl)methylidene]-2,3-dihydro-1H-isoindol-1-one}, C(14)H(12)N(2)O, was prepared by the base-catalysed condensation of phthalimidine with 2-formyl-1-methylpyrrole; yellow orthorhombic crystals, space group Pbca, were obtained from ethanol. The molecule is almost planar, having Z(-)antiperiplanar geome...
متن کامل3,6-Dihydroxy-2-(11-phenylundecanoyl)cyclohex-2-en-1-one from Virola venosa bark.
The structure of the title compound, C23H32O4, an arylalkanone isolated from the petroleum ether fraction of the ethanol extract of the bark of Virola venosa, has been established by NMR spectroscopy and, for the first time, by X-ray structure analysis. Two independent molecules of the same enantiomer are present in the unit cell. Both molecules exhibit an intramolecular hydrogen bond, which ca...

In the crystal structure of the title compound, C(17)H(21)N(3)O(2)·2H(2)O, water mol-ecules are mutually O-H⋯O hydrogen bonded and form infinite chains propagating along the b axis. Neighboring chains are linked by the quinazoline mol-ecules by means of O-H⋯O=C hydrogen bonds, forming a two-dimensional network.
متن کامل12-(2-Hydroxy-6-oxocyclohex-1-enyl)-9,10-dihydro-8H-benzo[a]xanthen-11(12H)-one
In the xanthenone system of the title compound, C23H20O4, the pyran ring has a maximum deviation of 0.111 (1) Å from planarity and the outer cyclo-hexene ring exhibits a puckered conformation. The three methyl-ene C atoms of the cyclo-hexene ring bonded to the pyran unit are disordered over two sets of sites [occupancies = 0.570 (3) and 0.430 (3)]. In the crystal, mol-ecules are linked by C-H⋯O...
متن کامل3,15-Dimethoxy-10-methyltricyclo[9.4.0.02,7]pentadeca-1(11),2(7),3,5,9,12,14-heptaen-8-one
The title mol-ecule, C(18)H(16)O(3), contains three fused rings, of which the seven-membered cyclo-hept-2-enone ring has a screw-boat conformation. The two meth-oxy-phenyl rings make a dihedral angle of 50.4 (2)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds, leading to a three-dimensional supra-molecular architecture.
