1-ethyl-4-phenylethyl-1,4-dihydroquinoxaline-2,3-dione
(Wiley-Blackwell, 2004)
The title compound, C18H18N2O2, was synthesized by heating 2,4-dioxo-1,3-diphenyl-7,8-benzo-6-ethyl-9-(2-phenylethyl)-1,3,6,9- tetrazaspiro[4.4] nonane in toluene. The quinoxaline ring system is planar and the dihedral ...
1-(2-Morpholinoethyl)-1H-benzimidazole
(Wiley-Blackwell, 2004)
In the title compound, C13H17N3O, the benzimidazole ring is connected by an ethylene group to the morpholine ring, which has a chair conformation.
5-chloro-6-(2-fluorobenzoyl)-1,3-benzoxazol-2(3H)-one
(Wiley-Blackwell, 2004)
The title compound, C17H11ClFNO5, has a non-planar configuration. The crystal structure is stabilized by the formation of bifurcated N-H...O/O' hydrogen bonds involving the oxazole N atom and the two carbonyl O atoms of ...
Methyl 6-amino-5-cyano-2-methoxycarbonylmethyl-4-phenyl-4H-pyran-3-carboxylate
(Int Union Crystallography, 2004)
The pyran ring in the title compound, C17H16N2O5, adopts a boat conformation. The crystal packing is stabilized by intermolecular N-H...O and N-H...N hydrogen bonds.
