  N-guanidinosuccinimide, which then reacted with amines under microwave irradiation to afford 5. The desired products were successfully obtained in the reaction with aliphatic amines (primary and secondary) via a nucleophilic opening of the succinimide ring and the subsequent recyclization of the 1,2,4-triazole ring. This approach however failed when less nucleophilic aromatic amines were used. Therefore, an alternative

  提出了两条互补的制备N-取代的 3-(5-amino-1 H -1,2,4-triazol-3-yl)丙酰胺 ( 5 ) 的途径，并在 20 个代表性实例的合成中成功实现。这些方法使用相同类型的起始材料，即。琥珀酸酐、氨基胍盐酸盐及多种胺类。将试剂引入反应的途径和顺序的选择取决于胺的亲核性。第一条途径从制备N-胍基琥珀酰亚胺开始，然后在微波照射下与胺反应得到5. 通过琥珀酰亚胺环的亲核开环和随后的 1,2,4-三唑环的再循环，在与脂肪胺（伯胺和仲胺）的反应中成功获得了所需的产物。然而，当使用较少亲核芳族胺时，这种方法失败了。因此，采用了一种替代途径，即首先制备N-芳基琥珀酰亚胺，然后在微波照射下与氨基胍盐酸盐反应。使用NMR光谱和X射线晶体学研究了制备的1,2,4-三唑5中的环状原质互变异构。

  Methods and compounds, including compositions therefrom, are provided for determining the sequence of nucleic acid molecules. The methods permit the determination of multiple nucleic acid sequences simultaneously. The compounds are used as tags to generate tagged nucleic acid fragments which are complementary to a selected target nucleic acid molecule. Each tag is correlative with a particular nucleotide and, in a preferred embodiment, is detectable by mass spectrometry. Following separation of the tagged fragments by sequential length, the tags are cleaved from the tagged fragments. In a preferred embodiment, the tags are detected by mass spectrometry and the sequence of the nucleic acid molecule is determined therefrom. The individual steps of the methods can be used in automated format, e.g., by the incorporation into systems.

  提供了用于确定核酸分子序列的方法和化合物，包括从中制备的组合物。该方法允许同时确定多个核酸序列。这些化合物被用作标记，以生成与所选目标核酸分子互补的带标记的核酸片段。每个标记与特定的核苷酸相关，在优选实施例中，可以通过质谱法检测到。在通过顺序长度分离带标记的片段后，将从带标记的片段中切除标记。在优选实施例中，通过质谱法检测标记，并从中确定核酸分子的序列。该方法的各个步骤可以以自动化格式使用，例如通过纳入系统中。
