Descripción
Sumario:The title compound, C(19)H(17)NO(5), comprising two stereogenic C atoms of the same configuration, crystallizes in a centrosymmetric space group as a racemate. The pyran ring adopts a half-chair conformation, while the isoxazole ring adopts an envelope conformation with the C atom bonded to the meth­oxy­phenyl group as the flap. The dihedral angle between the mean plane of the pyran ring and the adjacent benzene ring is 5.86 (5)°. In the crystal, mol­ecules are linked by a weak C—H⋯O hydrogen bond, forming a chain along the a axis.
