摘要 为了寻找生物活性良好的噻唑基丙烯腈类化合物,利用2-氰甲基-4-(对氟苯基)噻唑(3)与取代氯甲酸酯(4)在碱存在下反应,合成了15个未见文献报道的2-[4-(对氟苯基)噻唑-2-基]-3-羟基-3-烃氧基丙烯腈化合物(5),其结构经核磁共振氢谱、质谱和元素分析表征。初步杀菌活性测试结果表明:所有化合物在试验浓度下均具有一定的抑菌活性,尤其对炭疽病菌Colletotrichumgossypii表现出较好的抑制活性,在质量浓度25mg/L下,所有化合物的抑制率均在50%以上,其中化合物5a、5e、5g、5k、5n和5o的抑制率在80%以上。 In order to find thiazolylacrylonitriles with good biological activity,fifteen novel 2-[4-(4-fluorophenyl)thiazol-2-yl]-3-hydroxy-3-hydrocarbyloxy acrylonitriles 5 were synthesized by reaction of 4-(4-fluorophenyl)-2-thiazoleacetonitrile 3 with substituted chloroformates 4 in the presence of base.The structures of these compounds were confirmed by 1H NMR,MS spectra and elemental analysis.The preliminary bioassay showed that all compounds exhibited certain fungicidal activity,especially showing good fungicid...
