akyl (aryl)amino methyl pyrimidinones. Subsequently, treatment of the phenyl aminomethyl derivative with formaldehyde under Mannich conditions produced the imidazopyridothienopyrimidine ring system. Similarly, reaction of the phenyl aminomethyl pyrimidonone with chloroacetyl chloride afforded a new heterocyclic system namely, cyclopentapyridothienopyrimidopyrazine. On the other hand, reaction of the amino-carboxamide
我们描述了一种通过 3-amino-1-thioxo-1 反应合成新型 4-cyano-1-morpholin-4-yl-6,7-dihydro-5H-cyclopenta[c]pyridine-3-thone 的简单方法,5,6,7-四氢环戊二烯[c]thiopyran-4-carbonitrile 与吗啉通过 Dimroth 重排。通过两种方法合成的 1-amino-5-morpholin-4-yl-7,8-dihydro-6H-cyclopenta[d]thieno[2,3-b]pyridine-2-carboxamide 作为用于合成与环戊二烯[d]吡啶环系统稠合的新型噻吩并嘧啶的通用前体。因此,氨基甲酰胺与丙二酸二乙酯、原甲酸三乙酯和环烷酮反应得到相应的稠合嘧啶杂环。另一方面,在二恶烷中使用氯乙酰氯对氨基甲酰胺进行氯乙酰化,产生氯乙酰氨基衍生物,该衍生物在与乙酸酐反应后发生环缩合
