For use as the internal standards in a quantitative analysis of natural jasmonic acid (JA) and methyl jasmonate (JAMe) by gas chromatography-mass spectrometry-selected ion monitoring, (±)-2-(2,3–2H2)JA and its methyl ester, (±)-2-(2,3–2H2)JAMe, were efficiently prepared from 2-(2–pentyl)-2-cyclopentenone through catalytic semi-deuteriogenation of acetylenic intermediates with deuterium gas in pyridine.
在通过气相色谱-质谱-选择离子监测法对天然
茉莉酸(JA)和甲基
茉莉酸甲酯(J
AMe)进行定量分析时,将(±)-2-(2,3–2H2)JA及其甲基酯(±)-2-(2,3–2H2)J
AMe作为内部标准,通过在
吡啶中用
氘气对
乙炔中间体进行催化半
氘代反应,从2-(2–戊基)-
2-环戊烯酮中有效制备出(±)-2-(2,3–2H2)JA及其甲基酯(±)-2-(2,3–2H2)J
AMe。
