Operationally simple Au(I)-catalyzed intramolecular hydroarylation (IMHA) reactions of terminal alkynes that proceed in high yield and under very mild conditions are described. These processes involve low catalyst loadings, mild reaction temperatures, and short reaction times, require no cocatalysts or additives, and allow for the generation of a number of important heterocyclic motifs from readily
描述了操作简便的Au(I)催化的末端炔烃分子内氢芳基化(IMHA)反应,该反应以高收率和在非常温和的条件下进行。这些过程涉及低催化剂负载,适度的反应温度和短的反应时间,不需要助催化剂或添加剂,并允许从容易获得的起始原料中产生许多重要的杂环基序。
