Description
Summary: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—H...O hydrogen bond between the amino group and the vicinal carbonyl group generates an S(6) ring. Intermolecular C—H...O interactions contribute to the stability of the crystal structure.
