چکیده
In the title compound, C22H19Br2NO3, the central oxo-cyclo-hexane ring is in a twist-boat conformation; all the substituents (one eth-oxy-carbonyl and two aryl groups) are located in equatorial orientations. One of the -CH2- groups and the opposite -CH- group bearing a bromo-benzene substituent form the flagpoles of the twist-boat. The dihedral angle between the aromatic rings is 76.4 (4)°. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into C(5) chains propagating in the [010] direction. A short Br⋯O contact of 3.254 (4) Å is observed.
