Abstract

Two hitherto unknown fusaricidins were obtained from fermentation broths of three strains. After structure elucidation based on tandem mass spectrometry and NMR spectroscopy, fusaricidin E was synthesized to confirm the structure and the suggested stereochemistry. The synthesis was based on a new strategy which includes an efficient access to the 15-guanidino-3-hydroxypentadecanoyl (GHPD) side chain from erucamide.

摘要

从三株菌株的发酵液中获得了两种此前未知的镰刀菌素。基于串联质谱和核磁共振光谱对其结构进行解析后,合成了镰刀菌素E以确认结构和所提出的立体化学。该合成基于一种新策略,该策略包括从芥酸酰胺高效获得15-胍基-3-羟基十五烷酰基(GHPD)侧链。
