6β,8β-Dihydroxyeremophil-7(11)-en-8α,12-olide
The title compound, C(15)H(22)O(4), an eremophilane sesquiternoid, was isolated from the roots of Ligularia virgaurea. Both six-membered rings (A and B) adopt chair conformations and the five-membered ring is almost planar (r.m.s. deviation = 0.016 Å). The two methyl and two hydroxy groups adopt a...

| Sumario: | The title compound, C(15)H(22)O(4), an eremophilane sesquiternoid, was isolated from the roots of Ligularia virgaurea. Both six-membered rings (A and B) adopt chair conformations and the five-membered ring is almost planar (r.m.s. deviation = 0.016 Å). The two methyl and two hydroxy groups adopt a syn conformation and the A/B ring junction is cis-fused. An intramolecular O—H⋯O hydrogen bond generates an S(6) ring. In the crystal, O—H⋯O hydrogen bonds link the molecules into [100] chains. |
