摘要：

The spectroscopically uncharacterized title compound, C15H15NO5, has been identified crystallographically. The assignment of a cyano substituent in preference to the isocyano (isonitrile) alternative can be made on the basis of the refinement and the observed geometry. The pyran ring has a half-chair conformation. The methoxy and acetate ester substituents lie, respectively, approximately in and perpendicular to the aromatic ring.
