3-{2-[(3-Phenyl-quinoxalin-2-yl)-oxy]ethyl}-1,3-oxazolidin-2-one.

ABSTRACT: The asymmetric unit of the title compound, C(19)H(17)N(3)O(3), consists of two independent mol-ecules that are disposed about a pseudo-centre of inversion. The plane of the phenyl substituent is twisted by 38.1?(1)° [43.6?(1)° in the second mol-ecule] out of the plane of the quinoxaline ring system. The five-membered ring of the substituent at the 2-position adopts an envelope conformation; the 5-CH(2) atom representing the flap lies out of the plane defined by the other four atoms [deviation 0.264?(7)?Å in the first mol-ecule and 0.291?(6)?Å in the second]. The dihedral angle between the five-membered ring and the 4-phenyl ring is 84.9?(1)° while that between the five-membered ring and the 5-phenyl ring is 65.6?(1)°.

Project description:Two isomers were isolated during the reaction between 3-methyl-quinoxalin-2-one and bis-(2-chloro-ethyl)amine hydro-chloride. The crystal structure of one isomer has already been reported [Caleb, Bouhfid, Essassi & El Ammari (2009). Acta Cryst. E65, o2024-o2025], while that of the second isomer is the subject of this work. The title compound, C(14)H(15)N(3)O(3), has a new structure containing oxazolidine and quinoxaline rings linked by an eth-oxy group. The main difference between the two isomers is the position of the oxazolidine group with respect to the quinoxaline system. The dihedral angle between the fused planar rings and the oxazolidin-2-one ring is 41.63 (8)° in the title mol-ecule.

Project description:In the title compound, C(23)H(24)N(4)O(3)·H(2)O, the 1,3-oxazoline ring is nearly planar [maximum deviation = 0.059?(2)?Å] and its mean plane is twisted by 30.12?(8)° with respect to the quinoxaline fused-ring system; the benzene ring is nearly coplanar with the quinoxaline fused-ring system [dihedral angle = 2.52?(2)°]. The water mol-ecule of crystallization is hydrogen-bond donor to an N atom of the quinoxaline ring system as well as an O atom of the oxazolinone unit, the two hydrogen bonds generating a chain running along the c axis.

(R)-2-Phen-oxy-1-(4-phenyl-2-sulfan-ylidene-1,3-oxazolidin-3-yl)ethanone.

Project description:The central 1,3-oxazolidine-2-thione ring in the title compound, C(17)H(15)NO(3)S, is approximately planar with maximum deviations of 0.036?(4) and -0.041?(5)?Å for the O and methyl-ene-C atoms, respectively. The dihedral angles formed between this plane and the two benzene rings, which lie to the same side of the central plane, are 86.5?(2) [ring-bound benzene] and 50.6?(3)°. The ethan-1-one residue is also twisted out of the central plane, forming a O-C-N-C torsion angle of 151.5?(5)°. The dihedral angle formed by the benzene rings is 62.8?(2)° so that overall, the mol-ecule has a twisted U-shape. In the crystal, mol-ecules are linked into supra-molecular arrays two mol-ecules thick in the bc plane through C-H?O, C-H?S and C-H?? inter-actions.

3-[2-(3-Methyl-2-oxo-1,2-dihydro-quinoxalin-1-yl)eth-yl]oxazolidin-2-one.

Project description: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.
