A series of benzamide derivatives (compounds 1–29) was synthesized based on the lead compound cuminic acid. The crystal structure of compound 11 was characterized by single crystal X-ray diffraction. The antifungal activity of the synthesized compounds was determined against seven plant pathogenic fungi, namely Rhizoctonia solani, Gibberella zeae, Helminthosporium maydis, Sclerotinia sclerotiorum, Botrytis cinerea, Coniothyrium diplodiella, and Coniothyrium lagenarium. Preliminary results indicated that most of them revealed significant antifungal activity. Among them, compound 22 showed the strongest activity and possessed better antifungal activity against H. maydis, S. sclerotiorum, and B. cinerea than carbendazim.
一系列苯甲酰胺衍生物(化合物1-29)是基于前导化合物枯酸合成得到的。化合物11的晶体结构通过单晶X射线衍射进行了表征。合成的化合物对七种植物病原真菌,即立枯丝核菌、玉蜀黍赤霉、玉蜀黍蠕孢、核盘菌、灰葡萄孢、双孢脐腐菌和葫芦脐腐菌,进行了抗真菌活性测定。初步结果表明,大多数化合物显示出显著的抗真菌活性。其中,化合物22表现出最强的活性,并且对H. maydis、S. sclerotiorum和B. cinerea的抗真菌活性优于多菌灵。
