NHC‐catalyzed (NHC=N‐heterocyclic carbene), highly asymmetric intermolecular Stetter reaction allows the atom‐economic and efficient formation of valuable α‐amino acid derivatives (see scheme); the key step is an intramolecular stereoselective protonation. For the first time, a β‐unsubstituted Michael acceptor was employed successfully in this kind of reaction, most importantly, with a broad range of
PROTONtype:高度不对称的分子间Stetter反应,经NHC催化(NHC = N-杂环卡宾),可经济高效地形成有价值的α-氨基酸衍生物(参见方案);关键步骤是分子内立体选择性质子化。第一次,β-未取代的迈克尔受体成功地用于这种反应中,最重要的是,它与多种不同的醛一起使用。
