  日期：2020.9

  A new method is presented for the synthesis of 2-aminoquinazolines, which is based on a Chan–Evans–Lam coupling of (2-formylphenyl)boronic acids with guanidines. Relatively mild conditions involving the use of inexpensive CuI as a catalyst and methanol as a solvent permit the application of the method to a wide range of substrates. Nonsubstituted, N-monosubstituted, and N,N-disubstituted guanidines

  提出了一种合成 2-氨基喹唑啉的新方法，该方法基于（2-甲酰基苯基）硼酸与胍的 Chan-Evans-Lam 偶联。涉及使用廉价的 CuI 作为催化剂和甲醇作为溶剂的相对温和的条件允许该方法应用于广泛的基材。未取代的、N-单取代的和 N，N-二取代的胍可用作反应物，以从容易获得的（2-甲酰基苯基）硼酸以中等产率得到相应的 2-氨基喹唑啉。

  play a critical role in modulating the function and expression of inflammatory cytokines related to rheumatoid arthritis (RA). Herein, we report the design, synthesis, and structure–activity relationships (SARs) of a series of novel quinazoline derivatives as JAK inhibitors. Among these inhibitors, compound 11n showed high potency against JAKs (JAK1/JAK2/JAK3/TYK2, IC50 = 0.40, 0.83, 2.10, 1.95 nM)

  Janus 激酶 (JAK) 在调节与类风湿性关节炎 (RA) 相关的炎症细胞因子的功能和表达方面发挥着关键作用。在此，我们报告了一系列作为 JAK 抑制剂的新型喹唑啉衍生物的设计、合成和构效关系 (SAR)。在这些抑制剂中，化合物11n对 JAK (JAK1/JAK2/JAK3/TYK2，IC 50  = 0.40、0.83、2.10、1.95 nM) 显示出高效能、理想的代谢特性和优异的药代动力学特性。在胶原诱导的关节炎（CIA）模型中，化合物11n表现出显着减少关节肿胀的作用，且安全性良好，可作为治疗炎症性疾病的潜在候选药物。
