In the title compound, C(29)H(26)N(2)O(2), one of the pyrrolidine rings in the pyrrolizine system is disordered, with site occupancies of ca 0.55 and 0.45. Both components of the disordered pyrrolidine ring adopt envelope conformations, whereas the other pyrrolidine ring adopts a twist conformation. The mol-ecules are linked into centrosymmetric dimers by N-H⋯O hydrogen bonds and the dimers are...

The title compound, C(23)H(16)N(2)O(3), exists in a Z configuration with respect to the acyclic C=C bond. The pyridine and phenyl rings are oriented at dihedral angles of 72.97 (4) and 45.05 (4)°, respectively, with respect to the almost planar indoline ring system [maximum deviation 0.080 (1) Å]. The pyridine and phenyl rings are oriented almost perpendicular to each other [dihedral angle 88.9...
متن کامل3-[2-(3-Methyl-2-oxo-1,2-dihydroquinoxalin-1-yl)ethyl]oxazolidin-2-one
The title heterocyclic compound, C(14)H(15)N(3)O(3), is a new synthetic mol-ecule containing oxazolidine and quinoxaline rings. It is built up from two fused six-membered rings linked to a five-membered oxazolidin-2-one ring by a C(2) chain. Both ring systems are essentially planar [maximum deviation = 0.894 (3) Å, r.m.s. deviation = 0.0043 Å]. The structure is held together by van der Waals fo...

The di-hydro-quinoxaline ring system of the title mol-ecule, C19H17N3O3, is approximately planar [maximum deviation = 0.050 (2) Å], the dihedral angle between the planes through the two fused rings being 4.75 (8)°. The mean plane through the fused-ring system forms a dihedral angle of 30.72 (5)° with the attached phenyl ring. The mol-ecular conformation is enforced by C-H⋯O hydrogen bonds. In t...
