The title compound, C(20)H(18)O(6), has been synthesized from 4-methoxyphenyl 3-O-benzoyloxy-alpha-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 center dot center dot center dot O hydrogen bonding is present in the crystal structure.
