In the title compound, C30H29BrN2O5, the -lactam ring is essentially planar, with the O atom displaced from this plane by 0.856 (9) Å, and forming dihedral angles of 24.35 (13) and 89.42 (14)° with the planes of the benzene substituent groups on this ring. The tetrahydropyran ring adopts an envelope conformation with the C atom bearing the -lactam ring as the flap. In the crystal, weak C-HO hydrogen bonds with carboxyl and tetrahydropyran O-atom acceptors give rise to a chain structure extending along the b-axis direction.
