3-Hydroxy-3a,6,8c-trimethylperhydrooxireno[2′,3′:7,8]naphtho[1,2-b]furan-7(2H)-one

Abstract

The title compound, C15H22O4, consists of two trans-fused six-membered rings and a trans-fused five-membered γ-lactone. The epoxy and hydroxyl groups are α-oriented. The cyclohexane rings adopt half-chair and chair conformations and the lactone ring is in an envelope conformation. The molecular structure is stabilized by one O—H...O and three C—H...O intramolecular hydrogen bonds.
