Abstract: In the title compound, C₁₉H₃₀O₃Si, both rings adopt a half-boat conformation. Overall, the molecule approximates a U-shape as the cyclo-2-ene-1,4-dione and butyldimethylsilyloxy substituents lie to the same side of the central cyclohexene ring; the methyl substituent lies to the other side of the molecule. In the crystal, linear supramolecular chains along the b axis are sustained by C-HO interactions.
