The potent spliceosome modulator pladienolide B, which bears 10 stereogenic centers, is prepared in 10 steps (LLS). Asymmetric alcohol-mediated carbonyl crotylations catalyzed by ruthenium and iridium that occur with syn- and anti-diastereoselectivity, respectively, were used to form the C20-C21 and C10-C11 C−C bonds.
具有 10 个立体中心的强效剪接体调节剂 pladienolide B 分 10 个步骤 (LLS) 制备。由钌和铱催化的不对称醇介导的羰基巴豆酰化反应分别具有顺和反非对映选择性,用于形成 C20-C21 和 C10-C11 C-C 键。
