Crystal structure of 4α-hydroxy-5α,8β(H)-eudesm-7(11)-en-8,12-olide monohydrate

Abstract

The title compound, C15H22O3·H2O, is a natural producr isolated from Chloranthus japonicus, which is a eudesmane sesquiterpenoid. The two trans-fused six-membered rings have chair confomations. In the crystal, O—H...O hydrogen bonds link the components into corrugated layers parallel to the bc plane. There are C—H...O interactions present within and between the layers.
