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 ...
In the title compound, C13H17N3O, the benzimidazole ring is connected by an ethylene group to the morpholine ring, which has a chair conformation.
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 ...
