Palladium-catalyzed carboamination reactions between aryl bromides and 4-(but-3-enyl)-substituted oxazolidin-2-ones are described. These transformations afford bicyclic oxazolidin-2-one derivatives that can be converted to trans-2,5-disubstituted pyrrolidines in one step. The starting materials are easily prepared from amino acid precursors, and products that contain up to three stereocenters are generated with >20:1 dr.
