An efficient RuPHOX−Ru catalyzed asymmetric cascade hydrogenation of 3-substituted chromones has been achieved under mild reaction conditions, affording the corresponding chiral 3-substituted chromanols in high yields with excellent enantio- and diastereoselectivities. A dynamic kinetic resolution process occurs during the subsequent hydrogenation of the C=O double bond, which is responsible for the
在温和的反应条件下实现了高效的 RuPHOX−Ru 催化 3-取代色酮的不对称级联氢化,以高产率提供相应的手性 3-取代色酮,并具有优异的对映和非对映选择性。在随后的C=O双键氢化过程中发生动态动力学拆分过程,这是不对称级联氢化的高性能的原因。
