Reported is a highly enantioselective Ni(0)‐catalyzed endo‐selective C−H annulation of 2‐ and 4‐pyridone, and 4‐pyrimidone with alkenes to provide drug‐relevant bicyclic heterocycle products. The use of a readily prepared chiral bulky NHC ligand (SIPE) for Ni catalyst and commercially available AlEt3 as co‐catalyst enhanced the practicality of this reaction.

镍/ NHC催化的吡啶酮和嘧啶与链状烯烃的对映选择性环化

报道了2-和4-吡啶酮和4-嘧啶酮与烯烃的高度对映选择性Ni(0)催化的选择性CH环化反应,可提供与药物相关的双环杂环产物。使用易于制备的手性庞大的NHC配体(SIPE)作为Ni催化剂和市售的AlEt 3作为助催化剂,可以提高该反应的实用性。
