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

ABSTRACT: The fused-ring system of the title compound, C(27)H(28)N(2)O(7), which comprises one five- and three six-membered rings, is approximately planar (r.m.s. deviation = 0.133?Å), the system being buckled along the axis passing through the O atoms of the anthraquinone portion of the mol-ecule. Within the anthraquinone portion, the two benzene rings are aligned at 7.3?(2)°. In the crystal, one of the tert-butyl groups is disordered over two sets of sites in a 1:1 ratio. Weak inter-molecular C-H?O hydrogen bonding is present in the crystal structure.

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.

Project description:In the title compound, C(21)H(16)N(2)O(3), the fused-ring system (r.m.s. deviation = 0.067 Å) is slightly buckled at the carbonyl C atom of the anthracenyl ring system [deviation = 0.177 (1) Å] that is closer to an allyl substituent. The two allyl units lie on the same side of the fused-ring plane but are oriented in opposite directions, with N-C-C-C torsion angles of 126.9 (2) and 116.7 (2)°. In the crystal, the mol-ecules are linked into chains propagating along the b axis by C-H⋯O hydrogen bonds.
