Abstract A facile new synthetic method for the preparation of a Type-A 1-arylnaphthalene lactone skeleton was developed and used to synthesise justicidin B and several derivatives. Key synthesis steps included Hauser–Kraus annulation of a phthalide intermediate and Suzuki–Miyaura cross coupling between a triflated naphthalene lactone intermediate and various potassium organotrifluoroborates. With two
摘要 开发了一种制备 A 型 1-芳基萘内酯骨架的简便新合成方法,并将其用于合成 justicidin B 和几种衍生物。关键的合成步骤包括苯酞中间体的 Hauser-Kraus 环化和三氟萘内酯中间体与各种有机三氟硼酸钾之间的 Suzuki-Miyaura 交叉偶联。除了两个例外,这些衍生物对脂多糖 (LPS) 诱导的小鼠巨噬细胞中一氧化氮 (NO) 的产生显示出显着的抑制作用。此外,包括 justicidin B 在内的几种化合物对六种人类肿瘤细胞系具有显着的细胞毒性。
