An efficient and scalable approach is described for the total synthesis of the marine natural product Et‐743 and its derivative lubinectedin, which are valuable antitumor compounds. The method delivers 1.6 % overall yield in 26 total steps from Cbz‐protected (S)‐tyrosine. It features the use of a common advanced intermediate to create the right and left parts of these compounds, and a light‐mediated remote C−H bond activation to assemble a benzo[1,3]dioxole‐containing intermediate.

抗肿瘤药Et-743和Lurbinectin的可扩展全合成。

描述了一种有效且可扩展的方法,用于海洋天然产物Et-743及其衍生物lubinectin的全合成,这是有价值的抗肿瘤化合物。该方法可从Cbz保护的(S)酪氨酸分26个步骤中获得1.6%的总收率。它的特点是使用常见的高级中间体来创建这些化合物的左右部分,并使用光介导的远程C H键活化来组装含苯并[1,3]二恶唑的中间体。
