  通过锌亚胺中间体卤化吡啶的3位

  摘要：

  吡啶卤化反应对于获得药物和农用化学品开发所需的大量衍生物至关重要。然而，尽管经过一个多世纪的合成努力，选择性官能化多种吡啶前体 3 位碳氢键的卤化过程在很大程度上仍然难以捉摸。我们报道了吡啶基开环、卤化和闭环的反应序列，其中无环锌亚胺中间体在温和条件下经历高度区域选择性卤化反应。实验和计算机理研究表明，卤素亲电子试剂的性质可以改变选择性决定步骤。使用这种方法，我们生产了多种 3-卤代吡啶，并演示了复杂药物和农用化学品的后期卤化。

  strategy for the syntheses of benzofuranoquinolines and its analogues via the irradiation of o-phenylfuranyl/thienylpyridines/pyrimidines in DCM with UV light at rt under an argon atmosphere is described. The mechanism of this reaction through the process of 6π-electrocyclization, [1,5]-hydrogen shift, and 1,3-eneamine tautomerism leading to H2 evolution was elucidated. Notably, the syntheses of cis-8b-methyl-8b

• Skeletal Editing of Pyrimidines to Pyrazoles by Formal Carbon Deletion

  日期：2022.12.7

  method for the conversion of pyrimidines into pyrazoles by a formal carbon deletion has been achieved guided by computational analysis. The pyrimidine heterocycle is the most common diazine in FDA-approved drugs, and pyrazoles are the most common diazole. An efficient method to convert pyrimidines into pyrazoles would therefore be valuable by leveraging the chemistries unique to pyrimidines to access diversified

  在计算分析的指导下，已经实现了一种通过正式碳缺失将嘧啶转化为吡唑的方法。嘧啶杂环是FDA批准的药物中最常见的二嗪，吡唑是最常见的二唑。因此，通过利用嘧啶独特的化学性质来获得多样化的吡唑，将嘧啶转化为吡唑的有效方法将是有价值的。已知一种将嘧啶转化为吡唑的方法，但其产率低且需要苛刻的条件。这里报道的转化在较温和的条件下进行，耐受多种官能团，并且能够在所得吡唑上同时区域选择性地引入N-取代。这种正式的一碳缺失方法成功的关键是嘧啶核心的室温三氟甲基化，然后是肼介导的骨骼重塑。

  selective modification of nitrogen heteroaromatics enables the development of new chemical tools and accelerates drug discovery. While methods that focus on expanding or contracting the skeletal structures of heteroaromatics are emerging, methods for the direct exchange of single core atoms remain limited. Here, we present a method for 14N → 15N isotopic exchange for several aromatic nitrogen heterocycles

  氮杂芳烃的选择性改性使新化学工具的开发成为可能，并加速了药物发现。虽然专注于扩展或收缩杂芳烃骨架结构的方法正在出现，但直接交换单核原子的方法仍然有限。在这里，我们提出了一种对几种芳香族氮杂环进行 14N → 15N 同位素交换的方法。这种氮同位素嬗变是通过氮原子的三飞化激活杂芳烃底物而发生的，然后是由 15个 N-天冬氨酸介导的开环/闭环序列，以实现氮原子的同位素交换。这种转化成功的关键是形成可分离的 15N-琥珀酰中间体，该中间体经过消除以得到同位素标记的杂环。这些转化发生在温和的条件下，化学和同位素产量高。
