We describe an improved synthesis of (−)-5,11-dideoxytetrodotoxin from an enone, which was used for synthesis of tetrodotoxin and its analogues in this laboratory. One of the major modifications was to establish a two-step guanidinylation of trichloroacetamide of a highly functionalized intermediate, which allowed us to prepare 15N2-labeled 5,11-dideoxytetrodotoxin for biosynthetic investigations.
我们描述了一种由烯酮改进的(-)-5,11-二脱氧河豚毒素的合成方法,该方法用于在该实验室中合成河豚毒素及其类似物。主要的修改之一是建立高度官能化中间体的三氯乙酰胺的两步胍基化,这使我们能够制备15 N 2标记的5,11-二脱氧河豚毒素用于生物合成研究。
