摘要：

In the title compound, C19H19ClO4, the dihydropyran ring and the cyclohexane ring adopt a half-chair conformation and a chair conformation, respectively. The cyclohexene ring has an envelope conformation with the central CH2 C atom as the flap. This atom is disordered over two positions [site-occupancy ratio = 0.744 (12):0.256 (12)] above and below the mean plane formed by the other five atoms. In the crystal, OH...O hydrogen bonds between hydroxy and carbonyl groups link molecules into chains propagating along [001].
