1,3-Di-3-pyridyl-2,3-dihydro-1H-naphth[1,2-e][1,3]oxazine.

ABSTRACT: In the crystal structure of the title compound, C(22)H(17)N(3)O, the oxazine ring has a half-chair conformation. The dihedral angles between the best least-squares plane through the pyridine rings and the planar part (O-C-C-C-N) of the oxazine ring are 72.14?(6) and 35.44?(7)°, the smaller angle involving the pyridine ring adjacent to the oxazine O atom. The mol-ecule has two stereogenic centers at the oxazine carbons, RS and SR. The crystal packing reveals that symmetry-related mol-ecules are linked by inter-molecular N-H?N hydrogen bonds to form chains parallel to the b axis.

Diethyl 2,6,11-trioxo-2,3-dihydro-1H-anthra[1,2-d]imidazole-1,3-diacetate.

Project description:The title compound, C(23)H(20)N(2)O(7), consists of three fused six-membered rings (A, B and C) and one five-membered ring (D), linked to two ethyl acetate groups. The four fused rings are slightly folded around the O=C?C=O direction of the anthraquinone system, with a dihedral angle of 3.07?(8)° between the fused five- and six-membered rings (C and D) and the terminal ring (A). The planes through the atoms forming each acetate group are nearly perpendicular to the mean plane of the anthra[1,2-d]imidazole system, as indicated by the dihedral angles between them of 79.94?(9) and 85.90?(9)°. The crystal packing displays non-classical C-H?O hydrogen bonds.
