A totalsynthesis of the putativestructure of nagelamide D from imidazole is described. A Stille cross-coupling is used to construct the bis imidazole skeleton, and the pyrrolecarboxamides are introduced via a double Mitsunobu reaction using a pyrrolehydantoin derivative. Discrepancies between the published spectroscopic data and that reported in the literature cast doubts either on the assigned structure
描述了从咪唑全合成 nagelamide D 的推定结构。Stille 交叉偶联用于构建双咪唑骨架,并通过使用吡咯乙内酰脲衍生物的双光信反应引入吡咯甲酰胺。已发表的光谱数据与文献中报告的数据之间的差异使人们对指定的结构或报告的数据产生怀疑。
