Deskripsi
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—H...O contact, which generates an S(6) ring motif. The crystal packing are stabilized by C—H...O interactions.
