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)° with the benzene ring. There is an intramolecular hydroxy–ketone O—H⋯O interaction between the two substituted cyclohexane rings as well as a short intramolecular phenol–methoxy O—H⋯O interaction.

A mixture of 4-hydroxy-3,5-dimethoxybenzaldehyde (2 mmol) and 4-hydroxy-3,5-dimethoxy (4 mmol) was stirred in water (2 ml) at 353 K. After completion of the reaction (TLC monitoring), the mixture was diluted with cold water (20 ml) and filtered to obtain the precipitated product which was further purified by recrystallization. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethanol solution.
The H atoms were fixed geometrically and allowed to ride on the attached non-H atoms, with O—H = 0.82–0.85 Å and C—H = 0.93–0.97 Å, and with Uiso(H) = 1.5 Ueq(C) for methyl H atoms and 1.2 Ueq(C) for all other atoms.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The development of new methods for the synthesis of 1,4-dihydropyridine derivatives is the motive for the current study, these derivatives being of interest because of their presence in numerous natural products and as well they possess a wide range physiological activities, e.g. they have calcium modulatory properties (Rose & Draeger, 1992), antibacterial activity (Davies et al., 2005) and fungicidal activity (Warrior et al., 2005). In order to prepare 1,4-dihydropyridine and research its bioactivity, the intermediate product C25H32O7, the title compound (I) was synthesized and its crystal structure is presented here. In the molecular structure of (I) (Fig. 1), the two fused 3-hydroxy-5,5-dimethylcyclohex-2-enone rings can be regarded as having envelope conformations, with atom C13 0.66 (6) Å out of the plane of atoms C10/C11/C12/C14/C15 and atom C21 0.65 (5) Å out of the plane of atoms C18/C19/C20/C22/C23. In addition, the two planes form dihedral angles of 57.6 (4)° and 53.9 (9)° with the phenyl ring. The methoxy group is nearly coplanar with the attached benzene ring [torsion angle C8—O2—C4—C5, -2.4 (5)°]. The crystal packing of the title compound is stabilized by two intra- cyclohexane ring hydroxy O—H···Oketone hydrogen bonds and a single intramolecular phenol O—H···O3methoxy interaction (Table 1).
