The stereoselectivity of the title reactions due to a hindering amino group in α-asymmetric aminoketones (1 and 2) and to an asymmetric center far away from the reaction center in β-(methylpiperidino)-ketones (11–14) has been studied. The aminoalcohols obtained (3–8 and 15–22) have been separated in most cases and the relative configurations attributed by NMR. Based on diastereomeric ratios, a N-coordinated
