Rhodium(iii)-catalyzed allylic C–H bond amination. Synthesis of cyclic amines from ω-unsaturated N-sulfonylamines

For the first time, intramolecular allylic amination was conducted using rhodium(III) according to an "inner-sphere" type mechanism with amines activated by only one electron-withdrawing group. The activation of C(sp(3))-H bonds was chemoselective and allows the access to a variety of substituted cyclic amines such as pyrrolidines and piperidines.
