3-Cyano-4-(p-tolyl)pyrido[3,2-c]cinnolin-2(1H) thione 3 was reacted with α -halo ketones, esters, or amides to give the intermediates, S-alkylated products 5b-h, respectively, which underwent intramolecular ring closure reactions with ethanolic sodium ethoxide to give thienopyridocinnolines 6a-h. Pyrimidothienopyridocinnolines 9 and 11 were obtained by treatment of oxazino compound 8 with hydrazine
3-Cyano-4-(p-tolyl)pyrido[3,2-c]cinnolin-2(1H) thione 3 与 α-卤代酮、酯或酰胺反应得到中间体,S-烷基化产物 5b- h,分别与乙醇乙醇钠进行分子内闭环反应,得到噻吩并吡啶并喹啉 6a-h。Pyrimidothienopyridocinnolines 9 和 11 是通过用水合肼和乙酸铵处理恶嗪基化合物 8 获得的。用乙酰丙酮、原甲酸三乙酯、二硫化碳、氯甲酸乙酯和乙酸酐处理肼衍生物 13,得到三唑并嘧啶并噻吩并吡啶啉 14-16、18 和 21,而用亚硝酸生成相应的四唑化合物 19。它们的嘧啶、三唑并嘧啶和杂环化系统。
