The problem to be solved by the present invention is to provide a highly-versatile method for producing a nitroxyl radical derivative, in which position-2 and position-6 in a TEMPO-based compound can be easily substituted, and further, a method for producing a nitroxyl radical derivative, in which a nitrogen nucleus is labeled with 15N.
In the present invention, the above-described problem can be solved by reacting a triacetoneamine derivative with ketone or aldehyde in the presence of ammonium salt or a 15N-labeled compound thereof to obtain a 2,6-substituted-4-piperidone derivative.
本发明要解决的问题是提供一种生产硝基自由基衍生物的高通用性方法,其中 TEMPO 基化合物中的位置-2 和位置-6 可以很容易地被取代,以及进一步提供一种生产硝基自由基衍生物的方法,其中氮核被 15N 标记。
在本发明中,通过在铵盐或其 15N 标记化合物存在下使三丙酮胺衍生物与酮或醛反应,得到 2,6-取代-4-哌啶酮衍生物,可以解决上述问题。
