In the title compound, C(15)H(16)BrNO(3)S, the boat form of the six-membered ring is almost symmetrical with respect to the ep-oxy bridge. The two five-membered rings generated by the ep-oxy bridge of the six-membered ring adopt envelope conformations, whereas the N-containing five-membered ring adopts a twisted conformation. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds.
