  一种4-氟取代芳基胺类化合物及其合成方法

  摘要：

  本发明公开了一种4‑氟取代芳基胺类化合物的合成方法，包括以下步骤：1)以酰基保护的苯基羟胺为底物，在极性溶剂中，以磺酰氟为氟源，在碱性条件下生成4‑氟取代苯胺类化合物；2)在稀酸性条件下或者Pd催化氢化进行脱保护基团，得到所述4‑氟取代芳基胺类化合物。本发明合成的4‑氟取代的苯胺类化合物，由于氟原子引入极大程度上增加其亲脂性，因此能广泛用于含氟药物、农药以及染料中间体的制备；同时，本发明采用的原料均为工业化产品，价廉易得，具有市售；通过本发明制得的4‑氟芳基苯胺收率高，能够以大于90％的收率得到纯度≥99％的产物；本发明操作简单，成本低廉的工艺十分适用于工业化，能够广泛推广使用。

  Various new N-aryl oxindoles were synthesized as intermediates for the preparation of pharmacologically active 2-(N-arylamino)-phenylacetic acids. Two novel approaches were explored for the construction of diarylamine and N-aryl oxindole core structures, in addition to Buchwald-arylamination and Smiles rearrangement.

  Indenoquinolinones have been synthesized from 2-haloquinoline-3-carbaldehyde through Pd-mediated simultaneous C–H (aldehyde) and C–X bond activation. DFT studies were performed to investigate the mechanistic pathway, and in situ UV–Vis studies indicate the presence of Pd(II) intermediate species. Aryne ligated Pd complex is actual intermediate in these reactions. Ligation of reactive aryne to Pd reduces probability of side reactions.

  Indenoquinolinones是通过Pd介导的同时C–H（醛）和C–X键活化，从2-卤代喹啉-3-羧醛合成的。进行了DFT研究以探讨机制路径，原位UV-Vis研究表明存在Pd(II)中间体物种。与Aryne结合的Pd复合物是这些反应中的实际中间体。反应性Aryne与Pd的结合降低了副反应的可能性。
