چکیده
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 forces [electrostatic interactions between dipoles, O⋯C = 3.002 (2) Å] between mol-ecules and by weak π-π stacking between symmetry-related mol-ecules, with an inter-planar distance of 3.579 Å and a centroid-centroid distance of 3.800 (1) Å. Inter-molecular C-H⋯O hydrogen bonds are also observed in the crystal structure.

The seven-membered ring in the title compound, C(20)H(19)N(3)O(3), adopts a boat conformation with the two phenyl-ene C atoms representing the stern and the methyl-ene C atom the prow. The dihedral angle between the best plane through the seven-membered ring (r.m.s deviation = 0.358 Å) and the phenyl substituent is 55.8 (1)°. The two rings at either ends of the ethyl chain are staggered [N-CH(2...

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...
