Heronamide C shows potent antifungal activity by targeting membrane phospholipids possessing saturated hydrocarbon chains with as‐yet‐unrevealed modes of action. In spite of their curious hypothesized biosynthesis and fascinating biological activities, there have been conflicts in regard to the reported stereochemistries of heronamides. Here, we describe the asymmetric total synthesis of the originally proposed
鹭酰胺是从海洋来源的放线菌中分离出来的与生物合成相关的代谢产物。Heronamide C通过靶向具有饱和烃链且迄今尚未揭示的作用方式的膜磷脂,显示出强大的抗真菌活性。尽管它们具有奇怪的假设生物合成和令人着迷的生物活性,但是据报道,其烯醇酰胺的立体化学仍存在冲突。在这里,我们描述了Heronamide C的最初提出和修改的结构的不对称全合成,明确证实了该分子的化学结构。我们还证明了从Heronamide C进行的非酶促合成Heronamides A和B的合成,不仅证明了假定的生物合成,而且证实了Heronamides A和B的正确结构。
