Depending on the steric hindrance of the ligand, a regioselective palladium-catalyzed diamination of unactivated alkenes, provides either amino-functionalized piperidines or pyrrolidines. 6-Endo diamination occurred with a less sterically hindered quinox ligand to afford 3-aminopiperidines, while 5-exo diamination occurred with a bulky pyox ligand to give amino-substituted pyrrolidines.
