The eudesmane-type terpenoid, C(20)H(30)O(5), isolated from Sclerorhachis platyrachis, has a deca-lin skeleton whose six-membered rings adopt chair conformations. The two methyl substituents occupy axial positions, whereas the other three substituents occupy equatorial positions. The hy-droxy group is an intra-molecular hydrogen-bond donor to the single-bond ester O atom; adjacent mol-ecules are linked through the carb-oxy-lic acid interacting with the hydroxyl group, forming a hydrogen-bonded c ...[more]
