Enantioselective synthesis of 6-methyloctanal and 8-methyldecanal, the characteristic aroma components in yuzu <i>Citrus junos</i>, and the analysis of their enantiomeric compositions in yuzu essential oil
8-methyldecanal are the characteristic aromacomponents of yuzu Citrus junos. However, their absolute configurations and enantiomeric compositions in yuzu essential oil have not been analyzed. A concise enantioselective synthesis of both aldehydes was successfully carried out to determine their absolute configurations and enantiomeric compositions. Both aldehydes in yuzu essential oil were found to be (S)-form
抽象的 6-甲基辛醛和8-甲基癸醛是柚子的特征香气成分。然而,柚子精油中它们的绝对构型和对映体组成尚未得到分析。成功地进行了两种醛的简明对映选择性合成,以确定它们的绝对构型和对映体组成。柚子精油中的两种醛均呈 ( S ) 型,对映体过量。
