6-naphthyridines was successfully achieved by cyclocondensation of ethyl 4-aminoquinoline-3-carboxylates with malononitrile. The pyrazolo[4,3-c]quinolines were synthesized by nucleophilic substitution and subsequent addition reaction of ethyl 4-chloroquinoline-3-carboxylates with different hydrazines. All new compounds were characterized by spectral and analytical methods. Graphical abstract
摘要通过将4-氨基喹啉-3-羧酸乙酯与丙二腈进行环缩合,成功地合成了新型苯并[ h ] -1,6-萘啶。通过亲核取代和随后的4-氯喹啉-3-羧酸乙酯与不同的肼的加成反应合成了吡唑并[4,3- c ]喹啉。所有新化合物都通过光谱和分析方法进行了表征。 图形概要
