The aminolysis of 1-methyl-5-nitropyrimidin-2(1H)-one furnished diimines of nitromalonaldehyde in good yields. One of the imino groups of the diimines was readily hydrolyzed on silica gel to give nitroenamines possessing a formyl group. These reagents behaved as the synthetic equivalent of unstable nitromalonaldehyde, affording azaheterocycles upon a treatment with hydrazines or diamines.
1-甲基-5-硝基吡啶-2(1H)-酮的氨解反应生成了较高产率的硝基丙二醛二亚胺。其中一个亚胺基团在硅胶上易于水解,得到具有甲酰基的硝基胺。这些试剂表现出不稳定硝基丙二醛的合成等效性,与肼或二胺反应时形成了氮杂杂环。
