چکیده

The crystal structures are reported for two unsubstituted arylnaphthalene lactones, 4-phenylnaphtho[2,3-c]furan-1(3H)-one (2), 9-phenylnaphtho[2,3-c]furan-1(3H)-one (3) and a non-aromatic dihydro arylnaphthene lactone, 3a,4-dihydro-9-phenylnaphtho[2,3-c]furan-1(3H)-one (5). There only minor differences in the geometrical parameters of these structures. However, certain cases, both isomers lactones (termed Type I II) were found same asymmetric unit cell.

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...

9-Chloro-1-methyl-7-phenyl-5,6-dihydro-13H-indolo[3,2-c]acridine

The title compound, C(26)H(19)ClN(2), is a 5,6-dihydro-13H-indolo[3,2-c]acridine prepared by condensation of a 2,3,4,9-tetra-hydro-1H-carbazol-1-one with 2-amino-benzophenone. The crystals undergo a destructive phase change upon cooling at varying temperatures between 270 and 200 K, depending on cooling rate and disturbance by vibration, thus indicating supercooling of the metastable room-tempe...

In the title compound, C(35)H(28)O(6)·C(7)H(8), the dihedral angle between the mean planes through the naphthalene ring systems of the dibenzo[a,g]fluorene moiety is 22.44 (3)°. The aromatic ring system of the naphthalenone unit is approximately perpendicular to the mean plane of the five-membered ring, forming a dihedral angle of 87.51 (5)°. An intra-molecular C-H⋯O hydrogen bond is observed. ...

9-Ethyl-2,3-dihydro-9H-carbazol-4(1H)-one

In the title compound, C(28)H(30)N(2)O(2), the cyclo-hexene ring system adopts a sofa conformation. The crystal structure is stabilized by C-H⋯O inter-actions between methyl H atoms of the ethyl substituents and the O atoms of carbonyl groups of adjacent mol-ecules, and by an inter-molecular carbon-yl-carbonyl inter-actions [3.207 (2) Å].

THE TITLE COMPOUND (TRIVIAL NAME: angustoline monohydrate), C(20)H(17)N(3)O(2)·H(2)O, features a fused-ring system formed by one five- and four six-membered rings. The nearly planar benzimidazole portion (r.m.s. deviation = 0.008 Å) and the nearly planar 2,7-naphthyridin-1-one portion (r.m.s. deviation = 0.022 Å) of the fused-ring system are slightly twisted, with a dihedral angle of 9.47 (8)°,...
