  批量捕获多个瞬态氮杂锂的“快照”

  摘要：

  流动微反应器技术的最新发展允许使用间歇式反应器无法实现的瞬态有机锂化合物。然而，在“卤素舞蹈”中捕获瞬态芳基锂仍然具有挑战性。本文报道了通过使用卤化锌二胺配合物开发微调的原位锌化，在间歇反应器中捕获这种短寿命的唑基锂。The reaction rate is controlled by the appropriate choice of diamine ligand. 该反应操作简单，可在 0 °C 下进行，在多克规模上具有高重现性。该方法适用于广泛的溴化唑，允许去质子功能化，用于生物活性唑的两种结构异构体的简明发散合成。

Conformational analysis and exploration of the structure–activity relationships of this new class of compounds led to the identification of potent GK-GKRP disruptors. Further optimization of this novel series delivered thiazole sulfone 93, which was able to

  葡萄糖激酶-葡萄糖激酶调节蛋白（GK-GKRP）复合物在控制肝脏中葡萄糖稳态方面起着重要作用。我们最近公开了一系列芳基哌嗪作为GK-GKRP复合物的体外和体内破坏剂，在2型糖尿病（T2DM）啮齿动物模型中具有功效。在这里，我们描述了一类新的芳基砜作为GK-GKRP配合物的破坏剂，其中中央哌嗪支架已被一个芳香族基团取代。构象分析和这种新型化合物的结构-活性关系的探索导致了有效的GK-GKRP干扰物的鉴定。该新型系列的进一步优化可提供噻唑砜93能够在体外和体内破坏GK-GKRP相互作用，从而增加未结合GK的细胞质水平。

  dihaloazoles can be monoarylated at a single C−X bond with high selectivity via Suzuki coupling. By changing the palladium catalyst employed, the selectivity can be switched for some dihaloazoles, allowing for Suzuki coupling at the other, traditionally less reactive C−X bond. These conditions are applicable to coupling of a wide variety of aryl-, heteroaryl-, cyclopropyl-, and vinylboronic acids with

  各种二卤代唑可以通过Suzuki偶联在单个C-X键上以高选择性单芳基化。通过改变所用的钯催化剂，可以切换一些二卤代唑的选择性，从而使Suzuki偶联在另一个传统上反应性较小的C-X键上。这些条件适用于以高选择性偶联各种芳基，杂芳基，环丙基和乙烯基硼酸，并能够以模块化的方式快速构建各种不同的二芳基唑阵列。
