制备方法与用途

用途

2-氯-5-氨基嘧啶是一种非常有用的嘧啶衍生物，也是一个重要的中间体化合物。

合成

将5-硝基脲嘧啶、三氯氧磷和有机碱按质量比1：5～10：3～7的比例混合后进行氯化反应，在30～105°C下反应2～6小时。反应完成后，冷却混合物并减压浓缩以去除多余的三氯氧磷。随后，加入水并用有机溶剂萃取，经过干燥和浓缩处理后得到中间产物2,4-二氯-5-硝基嘧啶。

  摘要：

  在这项工作中，我们报告了刚性大环三酰胺的合成及其作为选择性阴离子和金属受体的可调节离子识别特性。通过六甲基二硅叠氮化锂（LiHMDS）辅助环缩构反应制备了含二苯乙炔的环状三酰胺CTA-1b和三个带有官能甲氧基和嘧啶部分的环状三酰胺。CTA-1B显示强的结合亲和力，以氯-和我-阴离子，而CTA-2B显示了良好的结合亲和力的La 3+及Eu 3+的阳离子。通过将嘧啶和甲氧基结合到大环酰胺中，可以调节离子的选择性识别能力。
