A convergent, stereocontrolled total synthesis of (+)-tedanolide (1), an architecturally complex marine antitumor macrolide, has been achieved in 31 steps (longest linear sequence). Highlights of the synthesis comprise a highly efficient dithiane union, followed by an Evans-Tishchenko "oxidation" to enable formation of the seco-ester in the presence of an oxidatively labile dithiane, a highly refined
(+)-tedanolide (1) 是一种结构复杂的海洋抗肿瘤大环内酯,通过 31 个步骤(最长的线性序列)实现了聚合、立体控制的全合成。合成的亮点包括高效的二噻烷结合,然后是 Evans-Tishchenko“氧化”,以在氧化不稳定的二噻烷、高度精制的保护基策略以及化学和立体选择性C(18,19) 处的环氧化。
