• Cascade Approach to Highly Functionalized Biaryls by a Nucleophilic Aromatic Substitution with Arylhydroxylamines

  日期：2019.4.19

  A transition-metal free synthesis of highly functionalized 2-hydroxy-2′-amino-1,1′-biaryls from N-arylhydroxylamines has been developed. This operationally simple and readily scalable approach relies on a cascade of reactions that initially generates transient N,O-diarylhydroxylamines, via direct O-arylation, which then undergo rapid [3,3]-sigmatropic rearrangement and subsequent rearomatization to

  已经开发了由N-芳基羟胺合成的无过渡金属的高官能化2-羟基-2'-氨基-1,1'-联芳基。这种操作简单且易于扩展的方法依赖于一连串的反应，这些反应最初通过直接的O-芳基化反应生成N，O-二芳基羟胺，然后进行快速的[3,3]-σ重排，然后重新进行芳构化，形成NOBIN型产物。这些结构多样的官能化联芳基是在温和的条件下以良好或优异的分离收率得到的。
