epoxidation, while and the critical oxidative coupling was achieved under the PIFA/PTA conditions. Comparison of optical rotations for the synthetic and natural samples allowed for unequivocal assignment of the absolute configurations of the natural dracaenones.
首次以对映纯形式合成了几种龙脑烯酮。使用Evans醛醇缩合或手性氧化剂介导的不对称环氧化,在C-7的关键手性中心安装了明确的立体化学,同时在PIFA / PTA条件下实现了关键的氧化偶联。合成样品和天然样品的旋光度比较可以明确确定天然龙脑烯酮的绝对构型。
