The firsttotal syntheses of oresbiusin A in the (+)-, (–)-, and (±)-forms were accomplished in five steps with overall yields of ca. 70 %. The key intermediates with optical activity were generated through a Sharpless asymmetric dihydroxylation reaction. These efforts allowed us to establish the absolute configuration of this natural product with dextrorotary and a 2S configuration. In addition, the
(+)-、(-)-和(±)-形式的oresbiusin A的第一次全合成分五个步骤完成,总产率为约。70%。具有光学活性的关键中间体是通过 Sharpless 不对称二羟基化反应生成的。这些努力使我们能够建立这种具有右旋和 2S 构型的天然产物的绝对构型。此外,oresbiusin B 的两种对映异构体及其外消旋体的总合成分六个步骤完成,总产率为 58%。在这些化合物中,发现具有左旋旋转的非天然 oresbiusin A 在 H9 细胞中具有剂量依赖性的抗 HIV-1 活性,而其他化合物则无活性。
