isocyanide‐multicomponent reactions (I‐MCRs). The approach comprises the use of Passerini and Ugi reactions for assembling pseudo‐peptidic scaffolds (i.e., N‐alkylated and depsipeptides, peptoids) on carboxylic acid‐functionalized fullerenes. The method showed wide substrate scope for the oxo and isocyanide components, albeit the Ugi reaction proved efficient only for aromatic amines. The approach was successfully
为了为富勒烯的多样性导向装饰和连接提供一种有效且通用的方法,我们报告了第一个基于异氰酸酯-多组分反应(I-MCR)的C 60衍生化策略。该方法包括使用Passerini和Ugi反应在羧酸官能化的富勒烯上组装假肽支架(即N-烷基化和二肽,类肽)。该方法显示了羰基和异氰酸酯组分的广泛底物范围,尽管已证明Ugi反应仅对芳族胺有效。该方法已成功用于寡肽和聚乙二醇链(PEG)与C 60的连接,以及用于建造双天线以及PEG固定的二聚体富勒烯。对于所分析的所选化合物,形成1 O 2的量子产率显着。
