imidazo[2,1‐b][1,3,4]thiadiazole derivatives were synthesized. To this end, first 2‐amino‐1,3,4‐thiadiazole derivatives (compounds 2a and 2b), the starting materials, were synthesized with high yields (82% and 79%, respectively). Then imidazo[2,1‐b][1,3,4]thiadiazole derivatives (4–16), the target compounds, were synthesized from reactions of 2‐amino‐1,3,4‐thiadiazole derivatives (2a and 2b) with 2‐bromoacetophenone
在这项研究中,合成了一系列新的取代的咪唑并[2,1– b ] [1,3,4]噻二唑衍生物。为此,首先以高收率(分别为82%和79%)合成了起始原料2-氨基-1,3,4-噻二唑(化合物2a和2b)。然后咪唑并[2,1- b ] [1,3,4]噻二唑衍生物(4 - 16),目标化合物中,从2-氨基-1,3,4-噻二唑衍生物的反应(合成图2a和图2b)含2-溴苯乙酮衍生物(3a - 3i)(收率52%至71%)。所有合成的化合物的特征均是11 H NMR,13 C NMR,傅里叶变换红外,元素分析,质谱,和X射线衍射分析(化合物4 - 12,14,和15)的技术。体外对所有合成的化合物进行抗真菌活性测试。确定了针对某些植物病原体的目标化合物的抑制区,抑制百分比,最小杀真菌活性,最小抑制浓度和致死剂量值。根据生物学活性测试的结果,所有合成的化合物均显示出中等至高水平的抗真菌活性。进行理论计算以支持
