stereocontrolled total synthesis of the potent antimitotic agent (+)-discodermolide (1) has been achieved on gram scale. Key elements of the successful strategy include (1) elaboration of three advanced fragments from a common precursor (CP) which embodies the repeating stereochemical triad of the discodermolide backbone, (2) σ-bond installation of the Z trisubstituted olefin, exploiting a modified Negishi cross-coupling
有效的、高度收敛的、立体控制的有效抗有丝分裂剂 (+)-discodermolide (1) 的全合成已在克级实现。成功策略的关键要素包括 (1) 从共同前体 (CP) 精心制作三个高级片段,该片段体现了 discodermolide 主链的重复立体化学三元组,(2) Z 三取代烯烃的 σ 键安装,利用改进的 Negishi交叉偶联反应,(3) 利用高压合成后期鏻盐,以及 (4) Z 双取代烯烃和末端 (Z)-二烯的 Wittig 安装。
