3-a]pyridopyrimidin-9-ones, compounds I-VII, have been prepared via condensation of beta-keto esters with 2-aminopyridine derivatives, in the presence of polyphosphoric acid. The same technique has also been used to prepare diazepine compounds, VIII-X, by condensation of a gamma-keto ester with 2-aminopyridine derivatives. Details of synthetic procedures are shown. The new compounds have been characterized
一系列新的取代的8-fluro-4H-嘧啶[2,1-b] [1,3]苯并噻唑-4-酮()取代7-甲基-4H-异恶唑[2,3-a] pyrimidin-4-通过与β-酮酸酯缩合,制备取代的2-甲基-5,6,7,8-四氢-9H-异恶唑并[2,3-a]吡啶并嘧啶-9-,化合物I-VII。在多磷酸存在下的2-氨基吡啶衍生物。通过将γ-酮酸酯与2-氨基吡啶衍生物缩合,也使用了相同的技术来制备二氮杂化合物VIII-X。显示了合成程序的详细信息。这些新化合物已通过元素分析,GC-MS,FT-IR和NMR光谱进行了表征。已经研究并介绍了其中三种化合物的抗菌,抗真菌和抗癌(细胞毒性)活性。
