potent inhibitory activity against various RNA viruses including SARS-CoV-2. Herein, we present a concise total synthesis of carolacton, featuring the Krische allylation, Marshall coupling, NHK coupling, and RCM reaction as key elements. Additionally, we have synthesized three simplified carolacton analogues, one of which, namely, 14-demethyl-carolacton, exhibited notable antiviral activity. The present
Carolacton 是一种天然存在的 MTHFD1 抑制剂,对包括 SARS-CoV-2 在内的多种 RNA 病毒表现出有效的抑制活性。在此,我们提出了一种简明的 carolacton 全合成方法,以 Krische 烯丙基化、Marshall 偶联、NHK 偶联和 RCM 反应为关键要素。此外,我们还合成了三种简化的carolacton类似物,其中一种,即14-demethyl-carolacton,表现出显着的抗病毒活性。目前的工作为进一步探索 carolacton 及其类似物的治疗潜力铺平了道路。
