4–6. Also, the reactions of 5-amino-3,4-diphenylthieno[2,3-c]pyridazine-6-carboxamide with heterocyclic aldehydes and/or cycloalkanones were carried out and their products were identified. Moreover, some novel pyridazinothienopyrimidobenzimidazoles 14–17 were synthesized.
5-氨基-3,4-二苯基噻吩并[2,3-c]哒嗪-6-甲腈2a与丙二胺反应得到四氢嘧啶衍生物3。后一种化合物(3)经过一定的环缩合反应生成嘧啶并噻吩并哒嗪4-6。此外,还进行了5-氨基-3,4-二苯基噻吩并[2,3-c]哒嗪-6-甲酰胺与杂环醛和/或环烷酮的反应并鉴定了它们的产物。此外,合成了一些新的哒嗪并噻吩并嘧啶并苯并咪唑14-17。
