(Chemical Equation Presented) Another way to antidepressants: A series of β-secondary-amino ketone hydrochlorides (e.g. 1) were hydrogenated with remarkably high enantioselectivities by using a Rh complex containing P-chiral bisphospholane 2. These results establish a short and practical means for the synthesis of enantiopure N-monosubstituted γ-amino alcohols (e.g. 3), which are key intermediates in the synthesis of important antidepressants. (nbd = norbornadiene; TON = turnover number).
