A total synthesis of the reported structure of altenuisol is described. Comparison of the 1H NMR spectra of the synthesized compound and of the natural product revealed that the originally proposed structure was not correct. Consequently, two constitutional isomers were synthesized. The spectra of one of these compounds – a structure originally proposed as the structure of altertenuol – matched perfectly
描述了所报道的阿替尼醇结构的全合成。合成化合物和天然产物的 1H NMR 谱的比较表明最初提出的结构不正确。因此,合成了两种结构异构体。其中一种化合物的光谱——一种最初被提议为交替烯醇结构的结构——与天然产物的光谱完美匹配。因此,以间苯二酚和原儿茶醛为起始原料,以 10 步和 23% 的产率实现了阿替尼醇的全合成,其中最长的线性序列由 6 步组成。关键步骤是伴随内酯环形成的 Suzuki 偶联。交替性与交替性是否相同尚不能确定。
