  摘要：

  脂肪酸酰胺水解酶（FAAH）可以用于治疗与各种医学状况相关的疼痛。本文中，我们报告了一系列新颖的杂环N-羧酰胺FAAH抑制剂的设计和合成，这些抑制剂相对于单酰基甘油脂肪酶（MAGL）和羧酸酯酶（CEs）具有对FAAH的效力，代谢稳定性和选择性良好的一致性。使用苯并三唑基和咪唑基-N-羧酰胺系列进行的前导优化工作导致发现了临床候选药物8 l（3-（1-（环己基（甲基）氨基甲酰基）-1H-咪唑-4-基）吡啶1-氧化物; BIA 10-2474）作为FAAH的有效和长效抑制剂。但是，在使用化合物8 l进行的I期临床试验中，发生了意料不到且无法预测的严重神经系统不良事件，影响了五名健康志愿者，包括一名受试者的死亡。

  使内环化再次变得有利：通过叠氮化物基团对2-叠氮基芳基溴化物进行锂化/环化的概念上新的苯并三唑合成方法

  摘要：

  尽管苯并三唑是重要的且无处不在，但目前仅有一种概念上的合成方法：将两个邻氨基与亲电氮原子桥连。在此，我们公开了新的可行的选择-将内获得2 azidoaryl lithiums -cyclization原位从2 azidoaryl溴化物。使用二十四个带有各种烷基，烷氧基，全氟烷基和卤素取代基的实例来说明反应的范围。我们发现叠氮化物基团的导向作用允许在含有几个溴原子的芳基叠氮化物中进行选择性的金属-卤素交换。此外，（2-溴苯基）重氮甲烷经历类似的环化以生成吲唑。因此，芳基锂的环化包含邻-X = Y = Z基团是合成芳族杂环的一种新的通用方法。DFT计算表明，观察到的内选择性适用于经历“ 1,1-加成”（即叠氮化物，重氮化合物和异腈）的其他官能团的阴离子环化反应。与此相反，与遵循“1,2-加成”图案（氰酸酯，硫氰酸酯，异氰酸酯，异硫氰酸酯，和腈）的杂原子官能团的环化反应倾向于外-cyclizat
