In the title molecule, C14H14O5, the 1,3-dioxane ring is in an envelope conformation with the ring C atom common to the cyclohexane ring forming the flap. The other five atoms of the 1,3-dioxane ring are essentially planar [maximum deviation from the least-squares plane = 0.041 (3) Å] and form a dihedral angle of 13.75 (2)° with the furan ring. In the crystal structure, weak intermolecular C—H⋯O hydrogen bonds form extended chains along .
