efficient catalytic approach to the synthesis of N,N-dialkyl-2-alkynylanilines was developed by using Pd-catalyzed norbornene-mediated three-component reactions of haloarenes, alkoxyamines (RO-NR2), and alkynes. The procedure forms one CN bond and one CC bond efficiently in a one-pot manner from readily available starting materials. A number of 2-alkynylanilines with a broad range of functional groups
通过使用钯催化的卤代芳烃,烷氧基胺(RO-NR 2)和炔烃的三元反应,开发了一种有效的催化方法,用于合成N,N-二烷基-2-炔基苯胺。该方法由一锅法有效地从容易获得的起始原料中形成一个CN键和一个CC键。以良好至优异的产率提供了许多具有广泛官能团的2-炔基苯胺。
