Abstract

The mol-ecule of the title compound, C(20)H(32)O(4), is built up from three fused five-membered, six-membered and seven-membered rings. The five-membered ring has an envelope conformation, whereas the six- and seven-membered rings have chair conformations. The crystal structure is stabilized by strong inter-molecular O-H⋯O hydrogen bonds, forming a three-dimensional network. The absolute configuration was assigned on the basis of earlier chemical studies.

摘要

标题化合物C(20)H(32)O(4)的分子由三个稠合的五元、六元和七元环组成。五元环具有信封式构象，而六元和七元环具有椅式构象。晶体结构通过强分子间O-H⋯O氢键得以稳定，形成三维网络。绝对构型是根据早期化学研究确定的。
