Abstract—(±)-Botryodiplodin and (±)-epi-botryodiplodin acetates were prepared in good yields following a practical four step route. The method, for the construction of the strategic tetrahydrofuran ring, hinged on an unprecedented halogen atom transfer Ueno–Stork cyclization of an O-allyl a,a-dihalohemiacetal acetate, catalyzed by the redox complex CuCl/N,N,N0,N00,N00-pentamethyldiethylenetriamine.
