The first total synthesis of antifungal cyclic depsipeptide aureobasidin A is described. The synthesis was achieved mainly using bromotris(pyrrolidino)phosphonium hexafluorophosphate (PyBroP) as a coupling reagent. Peptide cyclization was carried out between L-allo-isoleucine (L-alle1) and L- Pro9 residues in the linear nonapeptide at the final step of the synthesis. Synthesized aureobasidin A was
描述了抗真菌环状二肽金黄色葡萄球菌素A的第一个全合成。合成主要使用溴化三溴(吡咯烷基)r六氟磷酸((PyBroP)作为偶联剂来完成。肽环化之间进行L-异基因-异亮氨酸(L-一个LLE 1)和L-临9个残基的线性九肽在合成的最后一步。就抗真菌活性和理化性质而言,合成的金黄色葡萄球菌素A与天然抗生素完全相同。还描述了由于N-甲基氨基酸引起的异常反应,恶唑啉介导的反应和N,O-酰基迁移。
