A stereospecific [3 + 3]-annulation of donor–acceptorcyclopropanes with nitrosoarenes under the influence of MgBr2 as a stoichiometric Lewisacid and reagent offers a novel approach to various structurally diverse C-8-brominated tetrahydroquinolines. In these cascades C–C, C–N, and C–Br bonds are formed. The reactions are easy to conduct and proceed under mild conditions, and the products can readily
