polyketide natural products anguinomycin C and D is reported based on key steps such as Negishi stereoinversion cross coupling, Jacobsen Cr(III)-catalyzed Hetero Diels-Alder reaction, Evans B-mediated syn-aldol chemistry, and B-alkyl Suzuki-Miyaura cross coupling. The configuration of both natural products was established as (5R,10R,16R,18S,19R,20S). Biological evaluation demonstrated that these natural
基于 Negishi 立体反转交叉偶联、Jacobsen Cr(III)-催化的 Hetero Diels-Alder 反应、Evans B 介导的 Syn-aldol 化学和 B-烷基等关键步骤,报道了聚酮化合物天然产物 Anguinomycin C 和 D 的制备铃木-宫浦交叉联轴器。两种天然产物的构型均建立为(5R、10R、16R、18S、19R、20S)。生物学评估表明,这些天然产物是核输出受体 CRM1 的抑制剂,导致 CRM1 介导的核蛋白输出在浓度高于 10 nM 时关闭。已经制备了 Anguinomycin 和 Leptomycin B (LMB) 的类似物,具有截短聚酮链的简单 α,β-不饱和内酯类似物 4 保留了大部分生物活性(抑制高于 25 nM)。
