The synthesis of a 15-membered macrocyclic triene containing all the required substituents of ring A of (+)-aphidicolin (1) is reported. This compound underwent a thermal transannular cycloaddition followed by an intramolecular aldol reaction to yield tetracycle 32 containing 8 chiral centers which is considered a key intermediate for the synthesis of (+)-aphidicolin and related analogs.
报道了包含(+)-蚜虫二酮(1)的环A的所有必需取代基的15元大环三烯的合成。对该化合物进行热环过环加成反应,然后进行分子内羟醛缩合反应,得到含有8个手性中心的四环32,这被认为是合成(+)-蚜虫环及其相关类似物的关键中间体。
