A useful and rapid access to libraries of N-arylbenzo[b]thieno[3,2-d]pyrimidin-4-amines and their pyrido and pyrazino analogues was designed and optimized for the first time via microwave-accelerated condensation and Dimroth rearrangement of the starting anilines with N′-(2-cyanoaryl)-N,N-dimethylformimidamides obtained by reaction of thiophene precursors with dimethylformamide dimethylacetal. The
通过微波加速的缩合反应和Dimroth重排设计并首次优化和优化了N-芳基苯并[ b ]噻吩并[3,2 - d ]嘧啶-4-胺及其吡啶基和吡嗪类似物的库的快速访问方法。通过噻吩前体与二甲基甲酰胺二甲基乙缩醛反应获得的N '-(2-氰基芳基)-N,N-二甲基甲亚胺与起始苯胺。估计了最终产物对五种蛋白激酶(CDK5 / p25,CK1δ/ɛ,GSK3α/β,DYRK1A和CLK1)的抑制力。N-芳基吡啶并[3',2':4,5]噻吩并[3,2 - d ]嘧啶-4-胺系列化合物(事实证明,图4a – j)对于开发新的CK1和CLK1激酶药理抑制剂具有特别的希望。
