Also discussed is the radical [3+2] cyclization of 1,1-divinylcyclopropanes with the potential for memory of chirality. The second chapter deals with the elimination of sulfonyl radicals during radical cyclizations of ene-sulfonamides. A family of polycyclic imines and a family of oxindole products were synthesized from polycyclic ene-sulfonamide precursors.} }
