| Summary: | The title compound {systematic name: 5,6,10-trihydroxy-7-isopropyl-1,1,4a-trimethyl-2,3,4,4a-tetrahydrophenanthren-9(1H)-one}, C20H26O4, is a diterpenoid which was isolated from the roots of Premna obtusifolia. The molecule has three fused six-membered rings; the cyclohexane ring is in a twisted-boat conformation and the cyclohexene ring adopts a sofa form. Intramolecular O—H...O hydrogen bonds generate two S(5) ring motifs. In the crystal, molecules are linked into infinite one-dimensional chains along the [001] direction by O—H...O hydrogen bonds and weak C—H...O interactions. |
