  prevalent in biologically and medicinally important molecules. Here we report that chiral N‐substituted 2‐pyridones were prepared by enantioselective, organocatalytic aza‐Michael additions of halogenated 2‐hydroxypyridines (pyridin‐2(1H)‐ones) to α,β‐unsaturated‐1,4‐dketones or 1,4‐ketoesters. The reactions were optimized by the choice of solvents and systematic screening of Cinchona alkaloid‐based bifunctional

  2-吡啶酮的结构普遍存在于生物学和医学上重要的分子中。在这里我们报道了手性的N取代的2-吡啶酮是通过将对卤化的2-羟基吡啶（吡啶2（1 H）-一个）进行对映选择性的有机催化氮杂Michael加成反应而制备的，形成α，β-不饱和的1,4,4-酮或1,4-酮酸酯。通过选择溶剂和系统筛选基于金鸡纳生物碱的双功能催化剂，可以优化反应，以实现出色的收率和对映选择性（最高收率98％，ee≥99％）。密度泛函理论计算为观察到的对映选择性提供了理论依据。使用通过该方法产生的手性迈克尔加合物，可以实现人鼻病毒蛋白酶抑制剂的正式合成。
