approaches to the synthesis of functionalized, pyrimido[5′,4′:4,5]thieno [3,2-c]pyridazines 2-18 , pyridazino[3′,4′:4,5]thieno[2,3-d]triazines 19, 20a,b and pyrido[3′,2′:4,5]thieno[3,2-c]pyridazines 22a,b are described. The sequence involves the heterocyclization of 6-amino-1,3-diphenyl-1,4-dihydrothieno[3,2-c]pyridazine-7-carboxamide (1) with appropriate reagents. The antimicrobial activity of some the newly
合成功能化嘧啶并[5',4':4,5]噻吩并[3,2-c]哒嗪2-18、哒嗪并[3',4':4,5]噻吩并[2,3]的可能方法描述了-d]三嗪19、20a、b和吡啶并[3',2':4,5]噻吩并[3,2-c]哒嗪22a、b。该序列涉及 6-氨基-1,3-二苯基-1,4-二氢噻吩并 [3,2-c] 哒嗪-7-甲酰胺 (1) 与适当试剂的杂环化。检查了一些新合成化合物的抗微生物活性。所有测试的化合物都证明具有抗菌和抗真菌活性。
