Abstract
An aza-Michael addition-asymmetric transfer hydrogenation tandem process provides chiral γ-secondary amino alcohols in high yields with high enantioselectivities. 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.
