These compounds were characterized by 1H- and 13C-NMR, MS spectrum, IR spectroscopy and elemental analysis. The structure of 2 was verified by 2D-NMR measurements, including gHSQC and gHMBC measurements. A single-crystal X-ray diffraction experiment indicated that compound 3, with the molecular formula C17H15N3O2, crystallized from a CH3OH/CH2Cl2 diffusion solvent system in a monoclinic space group P21/c
4-Benzyl-1,2,4-triazin-3,5(2H,4H)-dione (3-benzyl-6-azauracil, 2) 和 2,4-dibenzyl-1,2,4-triazin-3 ,5(2H,4H)-二酮 (1,3-dibenzyl-6-azauracil, 3) 由 1,2,4-triazin-3,5(2H,4H)-dione (6-azauracil, 3) 反应合成, 1) 在无水丙酮中通过 18-crown-6-ether 催化使用苄基溴和碳酸钾。在这些反应方法中,我们开发了更方便和有效的方法,以良好的收率提供化合物 2 和 3。这些化合物通过 1H- 和 13C-NMR、MS 光谱、IR 光谱和元素分析进行表征。2 的结构通过 2D-NMR 测量验证,包括 gHSQC 和 gHMBC 测量。单晶 X 射线衍射实验表明,分子式为 C17H15N3O2 的化合物 3,从
