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 کاملCrystal structure of 13-(2-methoxyphenyl)-3,4-dihydro-2H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione
In the title compound, C22H18N2O4, the three fused rings of the pyrazolo-phthalazine moiety are coplanar (r.m.s. deviation = 0.027 Å). The cyclo-hexene ring fused to the pyrazolidine ring, so forming the indazolophthalazine unit, has a half-chair conformation. The benzene ring is almost normal to the mean plane of the pyrazolo-phthalazine moiety, with a dihedral angle of 87.21 (6)° between thei...
متن کامل8-Phenyl-3,4,6,7,8,8a-hexahydro-1H-pyrrolo[2,1-c][1,4]oxazin-6-one
In the title compound, C(13)H(15)NO(2), the hexa-hydro-pyrrolo-[2,1-c][1,4]oxazine fragment is disordered over two conformations (A and B) in a 0.656 (5):0.344 (5) ratio. The five-membered ring is similarly disordered and adopts an envelope conformation in A, while in B this ring is nearly planar [maximum deviation = 0.088 (1) Å]. The six-membered rings in both A and B exhibit chair conformatio...
متن کامل2-(2-Chloropyrimidin-4-yl)-3,5,6,7,8,9-hexahydro-2H-1,2,4-triazolo[4,3-a]azepin-3-one
In the title compound, C(11)H(12)ClN(5)O, the triazolone and pyrimidine rings are almost coplanar [dihedral angle = 2.98 (14)°]. The total puckering amplitude Q(T) of the seven-membered lactam ring is 0.706 (3) Å.
متن کامل1-(1-Hydroxyethyl)-7,8-dihydroindolo[2,3-a]pyridine[3,4-g]quinolizin-5(13H)-one (angustoline) monohydrate from Nauclea subdita (Rubiaceae)
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)°,...
