classic macrolide, isolated from Lyngbya bouilloni, has shown moderate anticancer activity against several cancer cell lines. Here, we report the first total synthesis and stereochemical configuration reassignment of lyngbyaloside C. The synthesis highlights a one‐pot intermolecular ketene esterification reaction to form the crucial tertiary ester and tetrahydropyran. In addition, a novel and concise
从大花肉Lyn中分离出的经典大环
内酯类大花lide苷C已显示出对几种癌
细胞系的中等抗癌活性。在这里,我们报告了lyngbyaloside C的第一个全合成和立体
化学构型的重新分配。该合成突出显示了一个单分子间烯
酮酯化反应以形成关键的叔酯和
四氢吡喃。此外,使用区域和立体特异性亲电醚转移反应,描述了一种新的,简明的合成途径,可通往1,3- syn仲叔叔二醇片段。
