Abstract: In the title compound, C₂₇H₂₅NO₅, the pyran ring in the chroman-4-one moiety adopts a sofa conformation and the pyrrolidine ring adopts a twisted or half-chair conformation. The chromanone moiety makes a dihedral angle of 64.3  (1)° with the mean plane passing through the pyrrolidine ring. In the crystal structure, the molecular packing is stabilized by C-HO intermolecular interactions.
