The scope of the palladium-catalyzed carboamination reaction for the synthesis of 2-substituted pyrrolidines, piperidines, and morpholines was investigated. Formation of a 2,4-disubstituted pyrrolidine proceeded in high yield but with a diastereoisomeric ratio of only 2:5, favoring the cis-isomer. The diastereoselectivity is hence significantly smaller than that observed previously in the formation
