The absoluteconfigurations at C-3 and C-4 of dihydroherqueinone monomethylether were determined to be R and S, respectively, by the X-ray crystallography, with relation to the previously established 2′R-configuration of herqueinone. Also, the recently proposed configuration at C-4 of herqueinone was confirmed by relating it to dihydroherqueinone monomethylether.
通过 X 射线晶体学,确定二氢赫奎因酮单甲醚的 C-3 和 C-4 处的绝对构型分别为 R 和 S,与先前建立的赫奎因酮的 2'R-构型有关。此外,最近提出的 Herqueinone C-4 构型通过将其与二氢 Herqueinone 单甲醚相关联而得到证实。
