demonstrated by the labeling of eight biologically active compounds. Remarkably, enantiomeric purity was conserved in the labeled compounds, even though labeling took place in the vicinity of the stereogenic center. The level of isotopic enrichment observed is suitable for metabolomic studies in most cases. This approach is also perfectly adapted to tritium labeling because it uses a gas as an isotopic
一种高效的H / D交换方法,可将吡啶,喹啉,吲哚和烷基胺与D 2氘化描述了在Ru @ PVP纳米颗粒存在下的存在。通过涉及温和的反应条件和简单的过滤以回收标记产物的通用且简单的程序,22种化合物的同位素标记以良好的产率进行,具有很高的化学和区域选择性。通过标记八种生物活性化合物证明了该方法的可行性。值得注意的是,即使标记发生在立体异构中心附近,标记化合物中的对映体纯度仍保持不变。在大多数情况下,观察到的同位素富集水平适用于代谢组学研究。这种方法还完全适合to标记,因为它使用气体作为同位素源。除了将这些应用应用于具有生物学意义的分子之外,
