  合成带有部分氟化烷基的3-取代哌啶的方法

  摘要：

  提出了一种合成带有部分氟化烷基的3-取代哌啶的方法。该方法基于DAST介导的易得的2-溴代吡啶-3-基醇和酮的DAST介导的氟化反应，提供了2-溴-3-（1-氟烷基）吡啶和2-溴-3-（1,1-二氟烷基） ）吡啶，然后进行催化氢化。使用常见的多相Pd-，Pt-和Rh基催化剂研究了氢化步骤。发现在氟代烷基衍生物的情况下，吡啶核的还原伴随着加氢脱氟，这成为该策略的局限性。但是，该方法对1,1-二氟烷基衍生物的效果很好

  quinolines, dibenzofurans, and carbazoles. The precursors are heterocycles bearing a methyl ketone group ortho to an internal alkyne. They are commercially available or can be obtained in three to four classical and efficient reactions: Vilsmeier−Haack, Sonogashira (diversity point), Grignard, and Ley’s oxidation. Upon aminobenzannulation reaction—classical conditions being pyrrolidine neat or in a solvent

  强大的氨基苯甲酸酯化反应已用于合成氨基取代的喹啉，二苯并呋喃和咔唑。前体是带有与内部炔烃邻位的甲基酮基的杂环。它们可以商购获得，也可以通过三到四个经典有效的反应获得：Vilsmeier-Haack，Sonogashira（多样性点），Grignard和Ley's氧化反应。在进行氨基苯甲酸酯化反应时（典型的条件是纯净的吡咯烷或在溶剂中和4ÅMS的条件下），在某些情况下，随着烯胺的形成，会得到有趣的双取代喹啉，二苯并呋喃和咔唑。由于meta产生了取代的杂环，并且还不同于经典的杂环方法，经典的杂环方法是在含杂原子的环上进行封闭而不是形成苯环。
