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.

The title compound, C24H29NO7, is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The coumarin ring system and the fused pyran ring make a dihedral angle of 10.46 (8)°. A short intramolecular N—HO hydrogen bond between the amino group and the vicinal carbonyl group generates an S(6) ring. Intermolecular C—HO interactions contribute to the stability of the crystal structure.
