Crystal structure of 15,16-epoxy-7β,9α-dihydroxylabdane-13(16),14-dien-6-one

Abstract

In the title molecule, C20H30O4, both cyclohexane rings adopt chair conformations. In the crystal, molecules are connected by O—H...O hydrogen bonds forming chains along [100]. In addtion, an intramolecular O—H...O hydrogen bond forms an S(5) ring.
