A Friedel–Crafts-type alkylation reaction was studied between various pyrroles and α-polyfluoroalkylated cyclicimines that were activated by Lewis acids. The reaction proceeded under mild conditions and provided a high yielding synthesis of α-CF3-substituted pyrrolidines and piperidines as well as seven-membered analogues that contained a pyrrole ring. The unpredictably high β-selectivity for the

Catalytic enantioselective functionalization of 2-pyrrolyl acetic acid with trichloromethyl enones using isothiourea catalysis is reported, leading to a range of stereodefined diesters and diamides after nucleophilic ring opening with either methanol or benzylamine (30 examples, up to >95:5 dr and >99:1 er). Subsequent intramolecular Friedel–Craftsreaction allows access to dihydroindolizinones in high yields
