  Synthesis and Evaluation of 4-Aryl-2(1H)-quinolinones as Potent Amyloid β Fibrillogenesis Inhibitors

  摘要：

  4-Aryl-2(1H)-quinolinones were synthesized and evaluated in vitro as inhibitors of A beta(1-42) fibrillogenesis using a thioflavin T fluorescence method. The most potent anti-aggregating molecules (4b and 5c) were found among the derivatives bearing OH and/or OMe groups at C-4' (R-4) and/or C-6 (R-2) of the 4-aryl-2(1H)-quinolinone moiety. Furthermore, the derivative bearing 4'-F substituent (4f) proved to be a very active inhibitor.

  Under thermal conditions, 1,4,2-dioxazol-5-ones are known to undergo decarboxylation followed by Lossen’s rearrangement to yield isocyanates. Described herein is the in situ trapping of the resulting isocyanates with carbon nucleophiles to synthesize β-keto amides. Furthermore, a general and mild method for the conversion of the resulting β-keto amides into quinolin-2-ones is reported.

  在热条件下，已知 1,4,2-dioxazol-5-ones 会先脱羧，然后发生 Lossen 重排，生成异氰酸酯。本文描述的是用碳亲核试剂原位捕获所得异氰酸酯以合成β-酮酰胺。此外，还报道了一种将所得 β-酮酰胺转化为喹啉-2-酮的通用且温和的方法。
