against normal cells. Total syntheses of apoptolidinones A and D are reported. The efficient synthetic strategy leading to the apoptolidinones features construction of the common 20-membered macrolactone by an intramolecular Suzuki reaction and stereocontrolled aldol reactions establishing the C19/C20 and C22/C23 stereocenters. In contrast to apoptolidin A, the aglycones apoptolidinone A and D were shown
凋亡素 AD 是微生物次级代谢产物,对多种癌细胞系具有选择性细胞毒性,而对正常细胞无细胞毒性。报道了凋亡烷酮 A 和 D 的全合成。导致凋亡烷酮的有效合成策略的特点是通过分子内 Suzuki 反应和立体控制羟醛反应构建常见的 20 元大环内酯,从而建立 C19/C20 和 C22/C23 立体中心。与凋亡素 A 相比,当针对人肺癌细胞 (H292) 进行评估时,苷元凋亡素 A 和 D 被证明是非细胞毒性的。
