摘要
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 beta-hydroxyleucine, were constructed via iterative Matteson homologations. A fragment coupling of a tetrapeptide, a depsidipeptide building block, macrocyclization, Staudinger reduction, and N-acylation are further steps in the synthesis.
