abscisic acid (ABA) with deuterium atoms at non-exchangeable positions have been synthesized to be used as standards for quantitation of the plant hormone ABA by mass spectrometry and also to be employed as substrates for metabolism studies. Deuterium atoms were introduced in the side chain of the molecule, at C-4 and/or C-5, by deuteride or hydride reduction of a propargylic alcohol, an intermediate
已经合成了四种在不可交换位置具有
氘原子的
脱落酸 (ABA) 类似物,用作质谱法定量植物激素 ABA 的标准,也用作代谢研究的底物。通过炔
丙醇(合成中的中间体)的
氘化物或
氢化物还原,将
氘原子引入分子侧链的 C-4 和/或 C-5。同样,通过将包含标记的格利雅试剂与环
己二烯酮中间体共轭添加,在 C-8' 位置引入了
氘标记,从而提供具有一到五个
氘原子的特定同位素标记的 ABA 分子。版权所有 © 2002 John Wiley & Sons, Ltd.
