hydrogenation tandem process for preparation of chiral γ-secondary amino alcohols 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 amino alcohols. An advantageous feature of this tandem reaction
已经开发出了氮杂-迈克尔加成-不对称转移氢化串联工艺来制备手性γ-仲氨基醇。这一一锅串联过程涉及芳基取代的烯酮和胺的氮杂-迈克尔加成反应,形成芳基取代的γ-仲氨基酮,然后Ru催化不对称转移氢化,形成芳基取代的γ-仲氨基醇。该串联反应的有利特征在于其以高收率和高对映选择性提供了各种γ-仲氨基醇。
