Molander et al. prepared six-membered carbocyclic and some heterocyclic rings by radical cyclization of phenyl or ketyl-olefin radicals to unactivated double bonds promoted by samarium diiodide. 6a–c However, no nitrogen six-membered heterocycles were reported by this method. Parsons and Pettifer demonstrated that substituted pyrrolidines and piperidines could be formed using tin hydride-mediated cyclization of a variety of α- and β-homoallylamino ...
