为了发现高效、低毒的农药先导化合物, 以真菌几丁质为研究对象, 以取代苯甲酸、5-取代苯基-2-呋喃甲醇为起始原料, 设计合成了23个新型取代苯甲酰胺基硫代甲酸-(5-取代苯基-2-呋喃)-甲酯, 其结构经IR, 1H NMR和元素分析确证. 初步生测结果表明, 在50 μg/mL浓度下, 化合物对黄瓜褐斑菌、黄瓜灰霉菌、黄瓜枯萎菌表现出明显的防效, 尤其对于黄瓜灰霉菌, 大部分化合物的防效优于对照药剂40%菌核净WP.

To find new pesticide lead compounds with high activity and low toxicity, chitin was chosen as the research target. 23 novel N-benzoyl-thiocarbamic-O-(5-aryl-2-furanmethyl) ester were designed and synthesized from substituted benzoic acid and 5-aryl-2-furanmethanol. Their structures were confirmed by IR, 1H NMR and elemental analysis. The preliminary bioassay results indicated that some compounds showed obvious inhibition effects against Corynespora cassiicola, Botrytis cinereap-ers, Fusarium oxysporum, especially to Botrytis cinereapers in which most compounds showed higher inhibitory rate than control fungicide 40% WP dimethachlon.

Key words: benzoylureas, chitin, N-benzoyl-thiocarbamic-O-(5-aryl-2-furanmethyl) ester, fungicidal activ-ity
