anticipated product, highly functionalized cyclopropanes were obtained. These novel cyclopropane structures are the result of the concomitant 1,2-migration of a dithiane thioether moiety and the eventual displacement of the acetate group, followed by the cyclization of the silyl enol ether.Key words: tricycles, SN2' cyclization, inductiveeffect, cyclopropane.

Oxidation of 2-tributylstannyl-1,3-dithianes with metallic oxidants generates reactive species such as 1,3-dithian-2-yl radical and/or cation by eliminating the stannyl group. Those intermediates react with olefins to give the intermolecular addition products.
