2,10-Dihydroxy-13-methyl-13-azatetracyclo[9.3.1.02,10.03,8]pentadeca-3(8),4,6-triene-9,15-dione
In the title compound, C(15)H(15)NO(4), the n-methyl-piperidone ring adopts a chair conformation and both five-membered rings adopt a twist conformation. An intra-molecular O-H⋯O hydrogen bond is observed. Inversion-related mol-ecules are linked into R(2) (2)(10) dimers by pairs of O-H⋯O hydrogen bonds. The crystal structure is further stabilized by C-H⋯O hydrogen bonds.

In the title compound, C(18)H(20)N(2)O(3), the N-methyl-piperidone ring adopts a chair conformation. The pyrrolidine ring and the five-membered cyclo-pentane rings adopt envelope conformations. The five-membered ring of the ninhydrin system adopts an envelope conformation with the central C atom deviating by 0.217 (1)Å from the mean plane through the other atoms. The mol-ecular packing is chara...

In the title compound, C(14)H(10)O(2), the acenaphthene-quinone core is essentially planar, with an r.m.s. deviation of 0.0140 Å. In the crystal, mol-ecules are connected by π-π stacking inter-actions [centroid-centroid distances = 3.766 (3), 3.839 (3) and 3.857 (3) Å], forming columns parallel to the a axis.
