  The present disclosure relates to bifunctional compounds, which find utility as modulators of tau protein. 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.

• IF₅ affects the final stage of the Cl–F exchange fluorination in the synthesis of pentafluoro-λ⁶-sulfanyl-pyridines, pyrimidines and benzenes with electron-withdrawing substituents

  日期：——

  A difficult chlorine–fluorine (Cl–F) exchange fluorination reaction in the final stage of the preparation of pentafluoro-λ6-sulfanyl-(hetero)arenes having electron-withdrawing substituents has now been elucidated through the use of iodine pentafluoride. A major side-reaction of C–S bond cleavage was sufficiently inhibited by the potential interaction between F and I with a halogen bonding.

  Ligand-controlled reactivity plays an important role in transition-metal catalysis, enabling a vast number of efficient transformations to be discovered and developed. However, a single ligand is generally used to promote all steps of the catalytic cycle (e.g., oxidative addition, reductive elimination), a requirement that makes ligand design challenging and limits its generality, especially in relay

  配体控制的反应性在过渡金属催化中起着重要作用，可以发现和开发大量有效的转化。然而，单个配体通常用于促进催化循环的所有步骤（例如，氧化加成、还原消除），这一要求使得配体设计具有挑战性并限制了其通用性，尤其是在中继不对称转化中。我们假设具有金属中心的多个配体可用于顺序促进多个催化步骤，从而通过简单配体的简单组合来结合互补的催化反应性。通过这种中继催化策略（L/L*），我们在此报告了第一个高度区域选择性和对映选择性远程加氢芳基化过程。3 )-H芳基化过程。
