A Survey of Synthesis of Antimycins

抗霉素(antimycin)是一大类具有九元环双内酯的天然抗生素,最早发现于20世纪40年代末.在随后的50多年中不断地有新的成员被发现,到目前为止已多达26个.这类化合物的结构主要是通过抗霉素A3b来确定的,所以合成工作也是围绕该成员展开的.对文献中已有报道的合成工作加以综述,对各方法的主要优缺点也进行了简要的分析.

Antimycins are a large family of natural antibiotics featuring a nine-membered dilactone ring. The name of antimycin could be traced back to the late 1940＇s. Since then, new antimycins are continuingly added to the list of this interesting class of compounds, which now already includes as many as 26 closely related individuals. Probably due to structural determination was mainly done on antimycin A3, synthetic endeavors up to now are carried out exclusively on the A3 （mostly A3b）. The enantioselective syntheses spread over the last decades are reviewed, with the merits and shortcomings briefly discussed.
