The combination of chiral bicyclo[3.3.0]octadiene ligands, an active rhodium hydroxide complex, and neutral reaction conditions enabled a highly enantioselective rhodium-catalyzed arylation of aliphatic N-tosylaldimines in high yield. The application of this method is demonstrated by the enantioselective synthesis of chiral 2-aryl pyrrolidines and piperidines in a one-pot procedure.
