制备方法与用途

3-氟吡啶-2-羧酸主要用作有机合成和医药化学中的中间体，它在农药分子和过渡金属催化反应中是重要的三齿氮配体。此化合物的羧基基团可以通过多种方式转化：例如，在二氯亚砜的作用下转化为酰氯；在四氟化硫作用下转化为三氟甲基；或者在碱性条件下与叔丁醇钾反应生成相应的羧酸盐，常见的是乙醇中的反应。

合成方法

在氮气氛围中，将1,4-二氮杂双环[2.2.2]辛烷(0.111公斤; 989毫摩尔)溶解于甲基叔丁基醚(4升)中。随后，将混合物冷却至-45摄氏度，在此温度下缓慢滴加正丁基锂，并保持反应体系的温度低于-40°C。加入正丁基锂后，继续在-40到-45摄氏度下搅拌2小时，然后加入3-氟吡啶(0.08公斤; 824毫摩尔)的甲基叔丁基醚溶液(0.4升)，使反应在低温下进行约45分钟。接着，在-45摄氏度下继续搅拌4小时，向混合物中添加二氧化碳在四氢呋喃中的饱和溶液淬灭反应。将混合物保持在-60摄氏度搅拌30分钟后，加入甲醇(1.6升)，使浆料升温至20摄氏度，并用盐酸水溶液调节pH值至4-5。最后，在真空下浓缩有机层以得到目标产物。

  摘要：

  描述了一种高效且普遍适用的合成不同 [5,6]吡喃[2,3-c]吡唑-4(1H)-酮的方法，包括将1-取代或1,3-二取代的2-吡唑啉-5-酮与不同的卤代吡啶酰氯或与3-氯喹啉-2-酰氯反应，使用氢氧化钙和1,4-二噁烷。在合成吡唑[4′,3′:5,6]吡喃[2,3-c]吡啶-4(1H)-酮的过程中，中间体4-(3-氯异尼古丁酰)-1H-吡唑-5-醇未能自发环化，因此通过在DMF中用氢化钠处理，转化为相应的三环化合物。在用三氟醋酸处理相应的1-(4-甲氧基苄基)保护同系物后，得到了N1未取代的目标化合物。

  TLR7/8 dual inhibitor (1) and a TLR8-specific inhibitor (2) based on our previous screen targeting TLR8. Compound 1, bearing a benzanilide scaffold, was found to inhibit TLR7 and TLR8 at low micromolar concentrations. We envisioned making modifications on the benzanilide scaffold of 1 resulting in a class of highly specific TLR7 inhibitors. Our efforts led to the discovery of a new TLR8 inhibitor (CU-115)

  内体通行费样受体（TLR）7和8识别病毒单链RNA，一类咪唑并喹啉化合物，8-氧代腺苷，8-氨基苯并二氮杂卓，嘧啶和鸟苷类似物。目前有大量证据表明，TLR7特异性介导的慢性炎症与自身免疫进程有关。基于我们先前针对TLR8的筛选，我们确定了一种新的TLR7 / 8双重抑制剂（1）和TLR8特异性抑制剂（2）。发现带有苯甲酰苯胺支架的化合物1在低微摩尔浓度下抑制TLR7和TLR8。我们设想对1的苯甲酰苯胺支架进行修改产生一类高度特异性的TLR7抑制剂。我们的努力导致发现了新的TLR8抑制剂（CU-115），并鉴定了带有独特的二苯醚骨架的TLR7 / 8双重抑制剂（CU-72），具有优化TLR7选择性的潜力。鉴于TLR8在自身免疫中的作用，我们还优化了2的效价并开发了带有1,3,4-恶二唑基序的新型TLR8抑制剂。
