The total synthesis of (-)-macrolactin A, a 24-membered macrolide, has been achieved using a newly developed 1,3-diol synthon for the introduction of two key stereogenic centers. The synthon was derived from sequential use of the Noyori asymmetric reduction followed by chiral sulfoxide methodology. Tellurium-derived cuprate organometallics offered an efficient and highly stereoselective means for installation
(-)-macrolactin A,一种 24 元大环内酯,已使用新开发的 1,3-二醇合成子实现了全合成,以引入两个关键立体中心。合成子源自 Noyori 不对称还原的顺序使用,然后是手性亚砜方法。碲衍生的铜酸盐有机金属化合物为安装 C8 Z/E-二烯提供了一种高效且高度立体选择性的方法,而 C15 E/E 链段则来自 Julia-Lythgoe 烯化。Yamaguchi 内酯化用于以收敛方法保护大环,最长的线性序列为 19 步,从 Noyori 酒精 6 开始。
