natural product 2‐aryl‐4,5‐dihydrothiazole‐4‐carboxylic acid, a series of novel (R)‐2‐aryl‐4,5‐dihydrothiazole‐4‐carboxylic acid derivatives were designed and synthesized. Their structures were characterized by 1H NMR, 13C NMR and HRMS. The single crystal structure of compound 9b was determined by X‐ray diffraction analysis. The antifungal activities were evaluated for the first time. The bioassay results
根据天然产物2-芳基-4-5,5-二氢噻唑-4-羧酸的结构,设计和合成了一系列新颖的(R)-2-芳基-4,5-二氢噻唑-4-羧酸衍生物。它们的结构通过1 H NMR,13 C NMR和HRMS表征。化合物9b的单晶结构通过X射线衍射分析确定。首次评估了抗真菌活性。生物测定结果表明,大多数化合物表现出中等至良好的抗真菌活性。化合物13a(对Cercospora arachidicola Hori),13d(对链格孢菌(Alternaria solani))的抗真菌活性和16e(与花生油茶(Cercospora arachidicola Hori)相比)分别为61.9%,67.3%和61.9%,高于商品杀真菌剂百菌清和多菌灵中的16e。此外,化合物13d对测试的7种真菌表现出优异的抗真菌活性(在50 µg?mL下,分别为66.7%,77.3%,63.0%,87.9%,70.0%,70.0%和80
