For the first time, a method for the synthesis of 2,3-dihydropyrazine 1,4-dioxide derivatives was devised. The presented approach is based on the reaction of N,N′-(2,3-dimethylbutane-2,3-diyl)bis(hydroxylamine) with α-ketoaldehydes. A distinctive feature of the proposed protocol is the application of sulfate of the aforementioned bis-hydroxylamine in the considered condensation. The advantages of the
首次设计了2,3-二氢吡嗪1,4-二氧化物衍生物的合成方法。该方法基于 N,N'-(2,3-二甲基丁烷-2,3-二基)双(羟胺)与 α-酮醛的反应。所提出的方案的一个显着特征是在所考虑的缩合中应用上述双羟胺的硫酸盐。新开发的路线的优点是一步合成程序涉及容易获得的起始原料、原子经济性和反应混合物的简单后处理。通过X射线分析确认了所得产物之一的结构。
