to synthesize 13C internal standards for the quantification of 4-hydroxy-2(E)-nonenal (HNE), a lipid peroxidation product, and of the etheno-adducts possibly formed by HNE damage to DNA nucleobases. We designed an eight-step synthesis starting from ethyl 2-bromoacetate and giving access to 4-[(tetrahydro-2H-pyran-2-yl)oxy]-2(E)-nonenal. This compound is a precursor of HNE. The scheme was then used
这项工作的目的是合成 13C 内标,用于定量 4-羟基-2(E)-壬烯醛 (HNE),一种脂质过氧化产物,以及可能由 HNE 对 DNA 核碱基的损伤形成的乙烯加合物。我们设计了一个从 2-溴乙酸乙酯开始并获得 4-[(四氢-2H-吡喃-2-基)氧基]-2(E)-壬烯醛的八步合成。该化合物是 HNE 的前体。然后使用该方案生产13C前体[1,2-13C2]-4-[(四氢-2H-吡喃-2-基)氧基]-2(E)-壬烯醛。[1,2-13C2]-HNE通过酸脱保护获得。所有中间体和最终化合物均通过 IR、HRMS、1H 和 13C NMR 进行了全面表征。这是 HNE 的首次合成,它能够在确定的位置结合两个 13C 标记。版权所有 © 2008 John Wiley & Sons, Ltd.
