Abstract: The dihydropyran ring in the title compound, C₁₉H₂₂O₃, adopts a half-chair conformation and the cyclohexane ring is in a chair conformation. In addition to van der Waals interactions, the molecular packing in the crystal is stabilized by C-H interactions, involving the dihydropyran ring of the symmetry-related molecules.
