A convergent, enantiocontrolled total synthesis of the 15-membered macrolide, amphidinolide P, is described. The synthesis utilizes three nonracemic components for an efficient assembly of the macrolactone in 12 steps via the longest linear pathway. Key developments include studies of the Hosomi–Sakurai reaction for the formation of the C6–C7 bond, a “ligandless” palladium-mediated Stille cross-coupling
描述了 15 元大环内酯、amphidinolide P 的收敛、对映控制全合成。该合成利用三种非外消旋组分通过最长的线性途径在 12 步中有效组装大环内酯。主要进展包括研究 Hosomi-Sakurai 反应形成 C 6 -C 7键,“无配体”钯介导的乙烯基锡烷4和烯基溴5 的Stille 交叉偶联以产生高度官能化的二烯醇,以及通过中间体α-酰基烯酮的后期形成进行的热诱导的分子内内酯化。
