A simple combination of dichloro(para‐cymene)ruthenium(II) dimer, a chiral amino alcohol and isopropyl alcohol allowed for in‐situ generation of the bifunctional catalyst responsible for the transfer hydrogenation reaction of trifluoromethyl ketimines in excellent yields with high enantioselectivities (up to 93% ee). Herein, we describe the optimization, scope, limitations, and applications of the
通过简单地将二氯(对-异丙基)钌(II)二聚体,手性氨基醇和异丙醇组合,可原位生成双功能催化剂,该双功能催化剂可实现高收率和高对映选择性的三氟甲基酮亚胺的转移加氢反应。到93%ee)。在此,我们描述了该方法的优化,范围,局限性和应用。
