Abstract: The title compound, C26H33NO7, comprises a racemic mixture of asymmetric molecules containing one stereogenic centre. The dihedral angle between the mean planes of the fused pyran ring and the coumarin ring system is 8.12 (14)°. The molecular structure features a short N-HO contact, which generates an S(6) ring motif. The crystal packing are stabilized by C-HO interactions.
