    • Chemler has previously described enantioselective Cu-catalyzed intramolecular carboamination reactions of N -(arylsulfonyl)- N -(pent-4-enyl)amines that generate substituted tetrahydro-1 H -benzo[ e ]pyrrolo[1,2- b ][1,2]thiazinedioxides. These products can be transformed to enantiomerically enriched 2-(arylmethyl)pyrrolidines through reductive desulfonylation. See
