A total synthesis of an antifungal cyclic depsipeptide aureobasidin A was first achieved mainly using PyBroP1) as a coupling reagent. The synthetic cyclized product was completely identical with the natural antibiotic in all respects. Some unexpected reactions due to N-methylamino acid were also described.
抗真菌环状缩肽
金孢菌素A的全合成首次主要使用
PyBroP作为偶联试剂实现。合成的环化产物在所有方面与天然抗生素完全相同。还描述了一些由于N-甲基
氨基酸引起的意外反应。
