aminopyrazolo[3,4-b]pyridines 2a,b used as good synthons for the synthesis of 3-thiadiazolinylpyrazolo[3,4-b]pyridines 8a,b through their reactions with thiocyanatoacetophenone (6) and pyrido[2,3:3',4']pyrazolo[5,1-c][1,2,4]]triazines 5a-d via their reactions with several active methylene containing reagents: 3a,b, 12, 16, 20, 23a-d and 26a-c. All the structures of the newly synthesized heterocyclic compounds
3-重氮化氨基吡唑并[3,4-b]吡啶 2a,b 用作合成 3-噻二唑啉基吡唑并[3,4-b]吡啶 8a,b 的良好合成子,通过它们与硫氰酸根乙酰苯 (6) 和吡啶并[2, 3:3',4']吡唑并[5,1-c][1,2,4]]三嗪5a-d通过它们与几种活性亚甲基试剂的反应:3a,b, 12, 16, 20, 23a- d 和 26a-c。除了通过其他途径合成大多数新合成的杂环化合物外,新合成的杂环化合物的所有结构都是通过考虑IR,1 H NMR和质谱数据建立的。
