Abstract
In the title compound, C30H50O3, the three six-membered rings adopt chair, twist and twist-boat conformations. The five-membered ring is in a slightly distorted envelope conformation. The substituent on the five-membered ring is in an extended conformation, with its two hydroxyl O atoms forming an i ntramolecular hydrogen bond. One of these O atoms also forms an intermolecu lar hydrogen bond with the oxygen of the carbonyl group in a neighbouring m olecule.
