A facile and highly enantioselective approach towards 2-substituted 3-bromopyrrolidines has been developed. The process involves an amino-thiocarbamate catalyzed bromoaminocyclization of 1,2-disubstituted olefinic amides. The pyrrolidine products could readily be converted into other useful building blocks including a dihydropyrrole and a 2-substituted pyrrolidine.

Palladium-catalyzed regiodivergent allylic C−H functionalizations were established via remote substitution, which provides a novel model for the seldomly studied migratory Tsuji–Trost reaction. 1,4-Hydrofunctionalization of a conjugated diene intermediate was demonstrated to be feasible via a newly synthesized bisphosphine ligand.
