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

Abstract

The title compound, C20H18O6, 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.
