探索了取代2-氢噻吩-3-羰基酸酯的合成及其硅烷化的方法,并对反应条件进行了优化;以其为母体合成了20个未见有报道的噻吩甲酰胺衍生物;各噻吩甲酰胺衍生物的结构经1H NMR,13C NMR,HRMS或元素分析确证;其对小麦全蚀病病原菌的抑菌活性经平皿法进行了测试. 初步结构活性分析表明,噻吩甲酰胺胺基取代基结构的变化及其2位官能团的大小对小麦全蚀病病原菌抑制活性有显著的影响,其中化合物7b7d7l7m7o表现出了优异的抑菌活性. 该结果对抑菌先导化合物的设计具有一定的参考价值.

The procedures for synthesizing the substituted ester 2-hydrothiophene-3-carboxylate and its silanization were explored. The reaction conditions were optimized. And with the substituted thiophene as the framework, 20 new thiophene carboxamide derivatives were synthesized. The chemical structures of thiophene carboxamide derivatives were confirmed by 1H NMR, 13C NMR, HRMS or elemental analysis techniques. The inhibitory activity against Gaeumannomyces graminis var. tritici was evaluated in vitro by the plate method. The preliminary structure-activity relationship indicated that the substituent bonded to the amide nitrogen atom and the steric hindrance of the substituent at 2nd position of the thiophene carboxamide had a significant influence on the activity. The compounds 7b7d, 7l, 7m and 7o exhibited very high inhibitory activity. The results would be helpful for the design of lead compounds.
