2-(4-Methoxyphenoxy)-6-methyl-3-oxo-3,6-dihydro-2 H-pyran-4-yl benzoate

Abstract

The title compound, C ₂₀H ₁₈O ₆, has been synthesized from 4-methoxy­phenyl 3- O-benzo­yloxy-α- l-rhamnopyran­oside by oxidation on treatment with pyridinium dichromate in the presence of acetic anhydride. In the mol­ecule, the pyran ring adopts an envelope conformation with the O atom at the flap position. Weak inter­molecular C—H⋯O hydrogen bonding is present in the crystal structure.
