aminodehalogenation reactions using microwave assisted synthesis with experimentally set and proven conditions. This approach for the aminodehalogenation reaction was chosen due to its higher yields and shorter reaction times. The products of this reaction were characterized by IR, NMR and other analytical data. The compounds were evaluated for their antibacterial, antifungal and herbicidal activity. Compounds 3 (R
在这项工作中,一系列 15 N-苄胺取代的 5-氨基-6-甲基-吡嗪-2,3-二甲腈通过氨基脱卤反应使用微波辅助合成在实验设定和验证的条件下制备。选择这种氨基脱卤反应的方法是因为它的产率更高,反应时间更短。该反应的产物通过红外、核磁共振和其他分析数据进行表征。评估了这些化合物的抗菌、抗真菌和除草活性。化合物 3 (R = 3,4-Cl)、9 (R = 2-Cl) 和 11 (R = 4-CF3) 对结核分枝杆菌显示出良好的抗分枝杆菌活性 (MIC = 6.25 µg/mL)。发现亲脂性对于抗分枝杆菌活性很重要,并且根据克雷格图,化合物的苄基部分上的最佳取代是卤素或三氟甲基。对细菌或真菌的活性微不足道。所提出的化合物还抑制了菠菜叶绿体中的光合电子传递,活性化合物的 IC50 值在 16.4 至 487.0 µmol/L 的范围内变化。活性最高的物质是 2 (R = 3-CF3)、3 (R =
