Full details of the total syntheses of erythro-nordihydroguaiaretic acid, threo-(-)-saururenin and their analogues are presented. The syntheses were based on a unified synthetic strategy involving the Stobbe reaction, alkylation to construct the skeleton of lignans and resolution of the threo- and erythro-iso- mers. The syntheses were achieved in eight to nine steps from simple aromatic precursors
介绍了赤藓-北二氢愈创木酸,苏-(-)-saururenin及其类似物的总合成的全部细节。合成基于统一的合成策略,包括Stobbe反应,烷基化以构建木脂素骨架以及拆分苏型和赤型异构体。从简单的芳香族前体以八到九个步骤完成了合成,并通过这种途径获得了13个木脂素。在合成的木脂素中,有七种木脂素是天然产物。此外,七个天然产物中的三个是首次合成的。检查了13种木脂素对人上皮细胞,HSV-1基因和人白血病,肝,前列腺,胃和乳腺癌细胞中HIV Tat反式激活的影响。
