the structure–activity relationship. The NMR data of the synthesized compounds do not match that of the isolated sample, indicating that the structure of nicotlactone A remains to be reassigned. All the synthetic target compounds were evaluated for their anti-tobacco mosaic virus (anti-TMV) activity. Bioassay results indicated that (±)-8-demethylnicotlactone A displayed similar anti-TMV activity to
最初提出的 (±)-烟内酯 A 结构的合成是一种具有三个连续手性中心的强效抗病毒木脂素,从丙烯酸甲酯开始分 5 步合成。合成的关键步骤包括 In 催化的区域选择性烯丙基化和 Mn 催化的 Mukaiyama 水合反应。我们的合成策略还使我们能够获得其他三种差向异构体并研究构效关系。合成化合物的核磁共振数据与分离样品的核磁共振数据不匹配,表明烟内酯 A 的结构仍有待重新分配。评估了所有合成目标化合物的抗烟草花叶病毒 (anti-TMV) 活性。生物测定结果表明,(±)-8-去甲基烟内酯 A 显示出与市售药物宁南霉素相似的抗 TMV 活性,
