The title compound, C(24)H(29)NO(7), 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...

description The title compound, C(24)H(29)NO(7), 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.
