title: 1α,6β,7β,14β,15β-Penta-hydr-oxy-7α,20-ep-oxy-ent-kaur-16-ene.
abstract: The title compound, enmenol, C(20)H(30)O(6), a natural ent-kaurane diterpenoid, comprises five fused rings, four of which are six-membered. Cyclo-hexane ring A adopts a chair conformation, rings B and C adopt boat conformations, while ring D has an envelope conformation, and two intramolecular O-H⋯O interactions occur. In the crystal, inter-molecular O-H⋯O hydrogen bonds generate a two dimensional network.
