Abstract: In the title compound, C₂₈H₂₇NO₅, the pyran ring in the chroman-4-one moiety adopts a sofa conformation and the pyrrolidine ring adopts an envelope conformation. The chromanone moiety makes a dihedral angle of 79.1  (1)° with the mean plane passing through the pyrrolidine ring. In the crystal structure, the molecules in the crystal lattice are stabilized by C-HO intermolecular interactions.
