A Mn‐catalyzed diastereo‐ and enantioselective hydrogenation of α‐substituted β‐ketoamides has been realized for the first time under dynamic kinetic resolution conditions. anti‐α‐Substituted β‐hydroxy amides, which are useful building blocks for the synthesis of bioactive molecules and chiral drugs, were prepared in high yields with excellent selectivity (up to >99 % dr and >99 % ee) and unprecedentedly
在动态动力学拆分条件下,首次实现了Mn催化的α-取代的β-酮酰胺的非对映和对映选择性氢化。抗-α-取代的β-羟基酰胺是生物活性分子和手性药物合成的有用组成部分,以高收率,高选择性(高达> 99%dr和> 99%ee)和前所未有的高活性制备。(TON最高10000)。出色的立体选择性的起源已通过DFT计算得以阐明。
