Abstract: In the title compound, C37H34N2O7, both pyrrolidine rings adopt envelope conformations. The [beta]-lactam ring is close to planar (r.m.s. deviation = 0.0395 Å) and makes a dihedral angle of 83.35 (15)° with the furan ring. The O atom attached to the [beta]-lactam ring deviates by 0.187 (2) Å from the mean plane of the ring. The [beta]-lactam ring makes dihedral angles of 14.90 (15) and 27.72 (17)° with the meth­oxy­phenyl and phenyl rings, respectively. The crystal packing features C-H...O hydrogen bonds.
