Novel and sequential intermolecular radical additions of 2,3-cis-disubstituted 1,1-dibromo- and 1-bromocyclopropanes to electron-deficient olefins proceeded with high stereoselectivity, i.e., in an exo-face addition manner. This highly stereoselective addition was also applied to an intramolecular cyclization.
