title: (S)-3-Acetyl-3-[(R)-1-(4-bromo-phen-yl)-2-nitro-eth-yl]oxolan-2-one.
abstract: The title compound, C(14)H(14)BrNO(5), 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, mol-ecules are connected into chains along [010] via weak C-H⋯O hydrogen bonds.
