The title mol-ecule, C21H28O5, is composed of three six-membered rings (A/B/C) and a five-membered ring (D). Ring A adopts a 1α-sofa conformation, while rings B and C adopt chair conformations. Cyclo-pentane ring D adopts a 14α-envelope conformation. In the crystal, O-H⋯O hydrogen bonds lead to the...

Summary: | The title mol-ecule, C21H28O5, is composed of three six-membered rings (A/B/C) and a five-membered ring (D). Ring A adopts a 1α-sofa conformation, while rings B and C adopt chair conformations. Cyclo-pentane ring D adopts a 14α-envelope conformation. In the crystal, O-H⋯O hydrogen bonds lead to the formation of ribbons running along the a axis. The structure is further consolidated by C-H⋯O inter-actions, which link the molecules head-to-tail into ribbons along the a axis. |
