A practical method for the synthesis of 15N-labeled azines with a high degree of isotopic enrichment is described. Activation of azine heterocycles with an electron-deficient arene allows for the facile substitution of the nitrogen atom with a specifically designed 15N-labeled reagent that undergoes a canonical ANRORC-type mechanism. A wide range of azines can be converted to their corresponding 15N
描述了一种合成高度同位素富集的15 N 标记吖嗪的实用方法。用缺电子芳烃激活吖嗪杂环可以用专门设计的15 N 标记试剂轻松取代氮原子,该试剂经历典型的 ANRORC 型机制。使用这种方法可以将多种吖嗪转化为其相应的15 N 同位素同系物,并且还可以脱芳香得到还原的杂环同系物。还完成了15 N-solifenacin 的简短脱芳香形式合成,以证明该方法在生成标记药物方面的实际应用。
