3-Hydroxy-2-[(4-hydroxy-3,5-dimethoxyphenyl)(2-hydroxy-4,4-dimethyl-6-oxocyclohex-1-en-1-yl)methyl]-5,5-dimethylcyclohex-2-en-1-one

In the title compound, C25H32O7, the 3-hydroxy-5,5-dimethylcyclohex-2-enone rings adopt slightly distorted envelope conformations with the two planes at the base of the envelope forming dihedral angles of 57.6 ( 4) and 53.9 (9)degrees with the benzene ring. There is an intramolecular hydroxy-ketone O-H center dot center dot center dot O interaction between the two substituted cyclohexane rings as well as a short intramolecular phenol-methoxy O-H center dot center dot center dot O interaction.
