Caerulomycins, natural alkaloids with antimicrobial properties, have been previously synthesized starting with highly pre-functionalized building blocks or requiring many functional group manipulations. In this work, we report the first total synthesis of caerulomycin K, a diversely trifunctionalized pyridine readily assembled in three steps exploiting the recent advancements in the C–H activation of N-heterocycles
青霉素是一种具有抗菌特性的天然生物碱,之前已通过高度预功能化的结构单元或需要许多官能团操作来合成。在这项工作中,我们报告了青霉素 K 的首次全合成,这是一种多官能化的吡啶,利用 N-杂环 C-H 活化的最新进展,可通过三个步骤轻松组装。
