hydrogenation tandem process for preparation of chiral γ-secondary aminoalcohols has been developed. This one-pot tandem process involves an aza-Michael addition of aryl-substituted enones and amines to form aryl-substituted γ-secondary amino ketones, followed by a Ru-catalyzed asymmetric transfer hydrogenation to form aryl-substituted γ-secondary aminoalcohols. An advantageous feature of this tandem reaction
