  exclusively at the position ortho to the hydroxyl group, providing a convenient method to synthesize the desired products in high yields. The reaction proceeds under mild conditions and tolerates a wide range of functional groups. Mechanistic studies indicate that this transformation proceeds via either (1) a single-electron transfer process involving attack of an N-centered radical onto the phenol or

  A family of covalent kinetic stabilizer compounds that selectively and covalently react with the prominent plasma protein transthyretin in preference to more than 4000 other human plasma proteins is disclosed. A contemplated compound corresponds in structure to Formula I, below, where the various substituents are defined within, and reacts chemoselectively with one or two of four Lys-15 ε-amino groups within the transthyretin tetramer. The crystal structure confirms the binding orientation of the compound substructure and the conjugating amide bond. A covalent transthyretin kinetic stabilizer exhibits superior amyloid inhibition potency, compared to a non-covalent counterpart, and inhibits cytotoxicity associated with amyloidogenesis.

  本文介绍了一类共价动力稳定剂化合物家族，它们选择性地、共价地与突出的血浆蛋白转甲状腺素结合，而不是其他4000多种人类血浆蛋白。一种可考虑的化合物对应于以下的结构式I，其中各取代基在内部定义，并与转甲状腺素四聚体中的一个或两个Lys-15 ε-氨基基团发生化学选择性反应。晶体结构证实了化合物亚结构和结合酰胺键的结合方向。与非共价对应物相比，共价转甲状腺素动力稳定剂表现出优越的淀粉样抑制效能，并抑制与淀粉样生成相关的细胞毒性。

  An efficient copper-catalyzed solvent-switchable regioselective 1,2- or 1,6-addition of quinones with boronic acids has been developed. This novel catalytic protocol for the synthesis of various quinols and 4-phenoxyphenols was enabled by a simple solvent swap between H2O and MeOH. It features mild reaction conditions, simple and easy operation, broad substrate scope and excellent regioselectivity
