AbstractIntroducing amide functional groups under mild conditions has growing importance owing to the prevalence of such moiety in biologically active molecules. Herein, we disclose a mild protocol for the directed ruthenium‐catalyzed C−H aminocarbonylation with isocyanates as the amidating agents developed through high‐throughput experimentation (HTE). The redox‐neutral and base‐free reaction is guided by weakly Lewis basic functional groups, including anilides, lactams and carbamates to access anthranilamide derivatives. The synthetic utility of this transformation is reflected by large‐scale synthesis and late‐stage functionalization.
摘要由于生物活性分子中普遍存在酰胺官能团,因此在温和条件下引入酰胺官能团的重要性与日俱增。在此,我们通过高通量实验(HTE)公开了一种温和的以异氰酸酯为酰胺化剂的定向钌催化 C-H 氨基羰基化反应方案。在弱路易斯碱性官能团(包括苯胺类、内酰胺类和氨基甲酸酯类)的引导下,这种氧化还原中性的无碱反应可获得蒽酰胺衍生物。大规模合成和后期功能化体现了这种转化的合成效用。
