3a-Bromoperhydro-2,6a-Epoxyoxireno[e][2]Benzofuran

Abstract

In the title compound, C8H9BrO3, 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 third five-membered ring adopts a half-chair conformation. The refinement results suggest partial inversion twinning. © International Union of Crystallography 2007.
