The aqueous acid-catalysed intramolecular cyclization of dimethylated alliodorin (2) obtained from the heartwood of Cordia alliodora has been characterized by X-ray analysis as the unusual tetracyclic di-O-methyl hydroquinone title compound (8).A new synthesis of di-O-methylalliodorin (2) from a terminal methylallylic sulphide derivative of 2-geranil-1,4-dimethoxybenzene is described. Crystals of the title compound (8) are monoclinic, space group P21/c, unit cell dimensions a = 14.984(7), b = 5.206(4), c = 20.131(9) Angstroem, β = 99.77(1) deg, Z = 4.The structure was solved by direct methods and refined by least-squares calculations to an R value of 0.078 for 1 832 independent reflections measured on a diffractometer using Cu-Kα radiation.
