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.
