A series of 2-oxopyrimido[4,5-b]-, 2-thio[4,5-b]-, 1-(p-tosyl)pyrazolo[3,4-b]- and 1-(2',4'-dinitrophenyl)pyrazolo[3,4-b]-quinolines have been synthesized in good to excellent yields by environmentally benign solvent free microwave-induced techniques involving the condensation of 2-chloro-3-formylquinolines with urea, thiourea, p-toluenesulfonylhydrazide and 2,4-dinitrophenylhydrazine, respectively, using PTSA as a catalyst. All the synthesized compounds were evaluated for their antibacterial and antifungal activities. Most of the compounds showed the best activity against Escherichia coli and Pseudomonas aeruginosa.
通过环境友好的无溶剂微波诱导技术,分别使用对甲苯磺酸(PTSA)作为催化剂,使2-氯-3-甲酰基喹啉与尿素、硫脲、对甲苯磺酰肼和2,4-二硝基苯肼缩合,已合成了一系列2-氧代嘧啶并[4,5-b]-、2-硫代[4,5-b]-、1-(对甲苯磺酰基)吡唑并[3,4-b]-和1-(2',4'-二硝基苯基)吡唑并[3,4-b]-喹啉,产率良好至优异。对所有合成的化合物进行了抗菌和抗真菌活性评估。大多数化合物对大肠杆菌和铜绿假单胞菌表现出最佳活性。
