We describe the catalytic amination of β-(hetero)arylethyl ethers with amines using the organic superbase t-Bu-P4 to obtain β-(hetero)arylethylamines. The reaction has a broad substrate scope and allows the transformations of electron-deficient and electron-neutral β-(hetero)arylethyl ethers with various amines including pyrrole, N-alkylaniline, diphenylamine, aniline, indole, and indoline derivatives
我们描述了使用有机超碱t-Bu-P4的胺与β-(杂)芳基乙胺的催化胺化反应,以获得β-(杂)芳基乙胺。该反应具有广泛的底物范围,并允许缺电子和电子中性的β-(杂)芳基乙基醚与各种胺(包括吡咯,N-烷基苯胺,二苯胺,苯胺,吲哚和二氢吲哚衍生物)转化。机理研究表明,甲醇从底物上消除的两个反应途径是形成(杂)芳基烯烃,然后进行烯烃的加氢胺化。
