The first total synthesis of meliponamycin A, an antimicrobial cyclodepsipeptide isolated from Streptomyces, is reported. Two key building blocks, the substituted tetrahydropyranyl side chain and an azido analogue of protected β-hydroxyleucine, were constructed via iterative Matteson homologations.

报道了首次全合成美脂霉素 A,这是一种从链霉菌中分离出来的抗菌环缩酚肽。通过迭代 Matteson 同系化构建了两个关键的构建模块,即取代的四氢吡喃基侧链和受保护的 β-羟基亮氨酸的叠氮类似物。四肽的片段偶联、缩酚肽结构单元、大环化、施陶丁格还原和N-酰化是合成中的进一步步骤。
