8-Bromo-3-phenyl-3a,4-dihydro-3H-chromeno[4,3-c]isoxazole-3a-carbonitrile
In the title compound, C(17)H(11)BrN(2)O(2), the five-membered isoxazole ring has an envelope conformation with the C atom bearing the phenyl ring as the flap. The pyran ring has a half-chair conformation. In the chromeno ring system, the dihedral angle between the mean plane of the pyran ring and the benzene ring is 4.68 (2)°. The dihedral angle between the mean planes of the chromeno ring sys...

In the title compound, C(20)H(19)NO(5), the dihedral angle between the mean plane of the pyran ring (which has a half-chair conformation) and the benzene ring of the chromeno ring system is 7.21 (7)°. The dihedral angle between the mean plane of the chromeno ring system and the isoxazole ring is 21.78 (6)°, while the isoxazole ring forms a dihedral angle of 72.60 (8)° with the attached phenyl r...
متن کامل8-Bromo-3-(cyclopropanylcarbonyl)-5-methylindolizine-1-carbonitrile
The asymmetric unit of the title compound, C(14)H(11)BrN(2)O, contains three independent mol-ecules with very similar geometries. The dihedral angles between the side chain of the cyclo-propyl plane and the five-membered ring to which it is attached are 55.0 (2), 58.1 (2) and 60.2 (3)° for the three mol-ecules. Each mol-ecule forms an intra-molecular C-H⋯O hydrogen bond.

There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(26)H(17)FN(4)O(3), which differ in the dihedral angles between the aromatic rings (fluorophenyl, phenyl) and the pyrrolopyrimidine rings [0.6 (3)/76.3° and 73.7 (3)/64.6°, respectively]. The crystal structure is mainly stabilized by C-H⋯O and C-H⋯F inter-actions.
متن کامل3-(4-Fluorophenyl)-2-(2-naphthyloxy)-4-oxo-5-phenyl-4,5-dihydro-3H-pyrrolo[3,2-d]pyrimidine-7-carbonitrile
The title compound, C(29)H(17)FN(4)O(2), may be used as a new precursor for obtaining bioactive mol-ecules. There are two crystallographically independent mol-ecules in the asymmetric unit. The phenyl ring, 4-fluoro-phenyl ring and 2-naphth-yloxy ring are twisted with respect to the pyrrolopyrimidine ring by 52.30 (11)/49.05 (11), 80.94 (10)/88.36 (10) and 60.58 (7)/83.76 (7)°, respectively.
