In the title molecule, C17H18O5, which was prepared by the reaction of (R)-1,5-dioxaspiro[5.5]undecane-2,4-dione and 4-methoxybenzaldehyde with ethanol, the 1,3-dioxane ring is in a distorted envelope conformation with the spiro C atom forming the flap. The crystal structure is stabilized by weak intermolecular C-HO hydrogen bonds.
