Abstract: In the title compound, C₂₂H₂₁NO₅, the pyrrolidine ring and the five-membered ring in the indene group have envelope conformations, while the furan ring adopts a twist conformation. Weak intermolecular C-HO interactions link the molecules into centrosymmetric dimers. The crystal packing is further stabilized by van der Waals forces.
