The biological activities of shancigusin C (1) and bletistrin G (2), natural products isolated from orchids, are reported along with their first total syntheses. The total synthesis of shancigusin C (1) was conducted by employing the Perkin reaction to forge the central stilbene core, whereas the synthesis of bletistrin G (2) was achieved by the Wittig olefination followed by several regioselective
从兰花中分离出的天然产物 shancigusin C ( 1 ) 和 bletistrin G ( 2 ) 的生物活性及其首次全合成已被报道。 shancigusin C ( 1 ) 的全合成是通过 Perkin 反应形成中心二苯乙烯核进行的,而 bletistrin G ( 2 ) 的合成是通过 Wittig 烯化和几个区域选择性芳香族取代反应来实现的。两种合成都是根据木糖化学原理仅使用可再生原材料来完成的。 shancigusin C ( 1 ) 和 bletistrin G ( 2 ) 对抗肿瘤细胞的细胞毒性特性表明适合作为进一步结构变异的起点。
