Dimethyl 3,3'-[(4,5-dicyano-1,2-phenyl­ene)bis­(­oxy)]dibenzoate

In the title compound, C₂₄H₁₆N₂O₆, the dihedral angles between the central 4,5-dicyano-1,2-phenyl­ene unit [maximum deviation from planarity = 0.014 (4) Å] and the pendant benzene rings are 73.62 (5) and 84.08 (6)°.

2-[(8-Meth­oxy­carbonyl-4b,8-dimethyl-4b,5,6,7,8,8a,9,10-octa­hydro­phenan­thren-3-yl)amino]-3,5-dinitro­benzoic acid ethyl acetate monosolvate

The title compound, C₂₅H₂₇N₃O₈·C₄H₈O₂, has a diterpene skeleton in which the fused cyclo­hexane rings exhibit chair and half-chair conformations. An intra­molecular C—H...O hydrogen bond occurs. In the crystal, N—H...O, O—H...O and C—H...O hydrogen bonds are observed.
