Abstract:
The title compound, 2,9-bis(3-nitrophenyl)-1-azatricyclo[3.3.1.1(3,7)]decan-4-one, C21H19N3O5, has a tricyclic structure. The torsion angles may be used to describe the relationship of the carbonyl group to the adjacent faces, whereby it is seen that the angles on the face of the arylpiperidinone side [122.0 (3) and -122.0 (3) degrees ] are greater than those on the cyclohexanone side [-119.8 (4) and 119.9 (4) degrees ]. Although these differences may explain a facial selectivity during nucleophilic addition to the carbonyl group, the presence of the aryl rings is probably also important.
