entry toward thienamycin and related compounds. The copper(I)-mediated reaction between five-membered cyclic nitrones and terminal acetylenes, leading to the assembly of the basic skeleton of carbapenem antibiotics is described. The diastereoselectivity of this cycloaddition–rearrangement cascade, a process known as the Kinugasa reaction, with respect to the structure and configuration of both substrates
摘要 描述了五元环硝酮与末端乙炔之间的铜(I)介导的反应,导致碳青霉烯抗生素基本骨架的组装。讨论了这种环加成-重排级联的非对映选择性,该过程称为Kinugasa反应,涉及两种底物的结构和构型以及反应条件。所描述的方法在糖衍生的硝酮上的应用为硫霉素和相关化合物提供了有吸引力的入口。 描述了五元环硝酮与末端乙炔之间的铜(I)介导的反应,导致碳青霉烯抗生素基本骨架的组装。讨论了这种环加成-重排级联的非对映选择性,该过程称为Kinugasa反应,涉及两种底物的结构和构型以及反应条件。所描述的方法在糖衍生的硝酮上的应用为硫霉素和相关化合物提供了有吸引力的入口。
