title: 3-Hydr-oxy-3a,6,8c-trimethyl-perhydro-oxireno[2',3':7,8]naphtho[1,2-b]furan-7(2H)-one.
abstract: The title compound, C(15)H(22)O(4), consists of two trans-fused six-membered rings and a trans-fused five-membered γ-lactone. The ep-oxy and hydroxyl groups are α-oriented. The cyclo-hexane rings adopt half-chair and chair conformations and the lactone ring is in an envelope conformation. The mol-ecular structure is stabilized by one O-H⋯O and three C-H⋯O intra-molecular hydrogen bonds.
