A route to 3-arylpiperidines and 3-arylpyrrolidines involving radical 1,4- and 1,2-aryl migrations has been explored. For the piperidines, the first route requires a xanthate addition to an N-allylarylsulfonamide, followed by acetylation and treatment with lauroyl peroxide to give the corresponding 1,4-aryl transfer product. This compound can be converted into the desired piperidine derivative following
