Abstract

Mol-ecules of the title compound, C(23)H(26)Cl(2)O(4), are linked by hydrogen bonds between the hydroxyl O atom and the carbonyl O atom of a neighboring mol-ecule. The central hydropyran and fused cyclohexanone rings adopt half-chair conformations, while the fused hydroxycyclohexanone ring adopts a chair conformation.
