Abstract: The title compound, C14H14BrNO5, has two chiral C atoms. The quaternary C atom in the oxolanone ring has an S configuration, while the adjacent tertiary C atom has an R configuration. The oxolanone ring adopts an envelope conformation, with the flap C atom lying 0.298 (3) Å from the mean plane of the remaining four atoms. In the crystal, molecules are connected into chains along [010] via weak C-H...O hydrogen bonds.
