标题化合物为地高辛酮,C23 H30 O 5·H2O。在晶体中,分子间的O-H-O氢键有助于形成三维超分子结构。标题化合物具有三个稠合六元环(A、B、C)和两个非稠合五元环(D、E)。与其他结构一样,化合物核的A-B、B-C、C-D环结具有顺-反-顺构象,环A、B和C呈现椅式构象。
The title compound, digoxigenone, C23H30O5·H2O, was biotransformed from digoxigenin. In the crystal, intermolecular O—H⋯O hydrogen bonds contribute to the formation of a three-dimensional supramolecular structure. The title compound has three fused six-membered rings (A,B,C) and two non-fused five-membered rings (D,E). As in other structures, compound nucleus has a cis-trans-cis conformation for the A-B,B-C,C-D ring junctions with rings A, B and C exhibiting chair conformations.
