explores the asymmetric Michael addition reaction of 2-hydroxy-1,4-naphthoquinone and indole-3-ones catalyzed by cinchona alkaloids. This strategy utilizes 2-hydroxy-1,4-naphthoquinone and easily prepared indole-3-one as substrates, resulting in the synthesis of 23 unprecedented indolin-3-ones bearing a 1,4-naphthoquinone unit at the C2 position of indole under simple and mild reaction conditions, with
本文探讨了金鸡纳生物碱催化的2-羟基-1,4-萘醌和吲哚-3-酮的不对称迈克尔加成反应。该策略利用2-羟基-1,4-萘醌和易于制备的吲哚-3-酮作为底物,在吲哚的C2位上合成了23种前所未有的吲哚-3-酮,在吲哚的C2位上带有1,4-萘醌单元。反应条件简单温和,收率高达88%, ee 98%, dr >20:1。
