The total synthesis of gomisin A and schizandrin having natural configurations were accomplished for the first time. The key feature of these syntheses is a highly efficient intramolecular oxidative coupling of the intermediates 9 and 21, which can be obtained as both enantiomers in optically pure forms. The manipulation of the lactone moieties of 7 and 22 afforded natural enantiomers of schizandrin
首次完成了具有天然构型的gomisin A和五味子素的全合成。这些合成的关键特征是中间体9和21的高效分子内氧化偶联,可以以光学纯形式的两种对映异构体形式获得。操纵7和22的内酯部分可得到五味子素和gomisin A的天然对映体。
