An intramolecular anti-Markovnikov hydroamination of 1-(3-aminopropyl)vinylarenes occurred in the presence of [Rh(COD)(DPPB)]BF4 as catalyst to form 3-arylpiperidines in high yield. Reactants with substituents β to the amino group formed 3,5-disubstituted piperidines with high diastereomeric excess, whereas substituents in α and γ gave mostly enamines and isomerized starting materials.
