چکیده
The title compound, C18H24O2, was isolated from the leaves extract of Ficus carica L. The cyclo-hexane ring displays a chair conformation whereas the cyclo-hexa-1,4-diene ring adopts a flattened boat conformation with methyl C atoms at the prow and stern. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into supra-molecular chains propagated along the b-axis direction.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(19)H(25)NO(4). A single C-H⋯π inter-action and various inter-molecular contacts (2.65-2.83 Å) link the independent mol-ecules in the crystal structure. The N-containing six-membered ring assumes a twisted half-boat conformation.

The mol-ecule of the title compound, C(16)H(12)O(4), is almost planar; the two meth-oxy groups are slightly out of the plane of the anthraquinone ring system, with C-C-O-C torsion angles of -6.25 (19) and -10.22 (19)°. In the crystal structure, the mol-ecules adopt a herringbone arrangement and form face-to-face slipped anti-parallel π-π stacking inter-actions along the b axis, with an inter-pl...
