  在温和条件下用氧化铑催化剂氢化官能化吡啶

  摘要：

  哌啶是药物和农化化合物合成中使用最广泛的结构单元之一。吡啶的氢化是合成此类化合物的便捷方法，因为它只需要反应物、催化剂和氢源。然而，该反应对于官能化和多取代吡啶的还原仍然很困难。在这里，我们报道了使用稳定的市售铑化合物Rh 2 O 3来还原各种未保护的吡啶。该反应条件温和，底物范围广，具有实用价值。

  路易斯碱离核参数 NFB 及其在 MIDA-硼酸盐水解动力学分析中的应用

  摘要：

  已经测量了从广泛的路易斯碱硼烷加合物中置换 BH 3的奎宁环动力学。这些速率的参数化使得能够开发出离核量表 (NF B )，以量化和预测一系列其他路易斯碱基的离去基团能力。在多个系列 R' 3– n R n X (X = P, N; R' = 芳基, 烷基) 中观察到的可加性允许制定相关的取代基参数 ( n f PB , n f AB )，提供了一种方法计算N F B一系列路易斯碱基的值远远超出了实验得出的值。通过取代基参数n f PB与一系列烷基和芳基 MIDA 硼酸盐在中性条件下的水解速率的相关性，探索了核离性参数的效用。这允许鉴定具有接近反应中心的杂原子的 MIDA 硼酸盐，显示出不寻常的动力学不稳定性或水解稳定性。

• Iridium(III)-Catalyzed Direct Arylation of C–H Bonds with Diaryliodonium Salts

  arylation of complex compounds. Mechanistic studies by density functional theory calculations suggested that the sp(3) C-H activation was realized by a triflate-involved concerted metalation-deprotonation process, and the following oxidation of Ir(III) to Ir(V) is the most favorable when a bistriflimide is contained in the diaryliodonium salt. Calculations indicated that both steps are enabled by initial anion

  通过开发一种新的 Ir(III) 催化的 CC 交叉偶联，已经建立了一种将酮肟、含氮杂环、各种芳烃和烯烃中的 sp(2) 和 sp(3) CH 键直接芳基化的通用方法。该芳基化的关键取决于适当的催化剂选择和使用二芳基碘鎓Triflate Salts作为偶联伴侣。这种转化具有良好的官能团兼容性，可以作为复杂化合物后期 CH 芳基化的有力合成工具。通过密度泛函理论计算的机理研究表明 sp(3) CH 活化是通过三氟甲磺酸酯参与的协同金属化-去质子化过程实现的，当双氟甲磺酰亚胺包含在二芳基碘鎓盐中。

In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a VHL or cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds tau protein, such that tau protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tau. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tau protein. Diseases or disorders that result from aggregation or accumulation of tau protein are treated or prevented with compounds and compositions of the present disclosure.
