libraries of N‐arylbenzo[b]furo[3,2‐d]pyrimidin‐4‐amines (1) and their novel benzo[b]thieno[3,2‐d]pyrimidin‐4‐amine analogues (2) was investigated for the first time. Title compounds were obtained via microwave‐accelerated condensation and Dimroth rearrangement of suitable anilines with N′‐(2‐cyanaryl)‐N,N‐dimethylformimidamides obtained by reaction of benzo[b]furane and benzo[b]thiophene precursors with
可以快速有效地访问N-芳基苯并[ b ]呋喃[3,2 - d ]嘧啶-4-胺类库(1)及其新型苯并[ b ]噻吩并[3,2 - d ]嘧啶-4-胺类库首次研究了类似物(2)。通过苯并[ b ]呋喃和苯并[ b ]噻吩前体与N,N的反应获得的N '-(2-氰芳基)-N,N-二甲基甲亚胺通过微波加速缩合和合适的苯胺的Dimroth重排获得标题化合物-二甲基甲酰胺二甲基乙缩醛。这项工作还证明,控制良好的参数可以舒适地使用微波技术,既安全又有益于环境。本文获得的某些产品表现出有趣的体外抗增殖作用。
