with N, N-dimethylamino group and then reacted with the corresponding sulfonyl chlorides to synthesize N, N-dimethylarylsulfonamides. We herein designed and controlled synthesis of N, N-dimethylarylsulfonamide derivatives, and first reported the results of the nematicidal activity of 15 title compounds 3a-o against Meloidogyne incongnita in vitro, respectively. Among all of the title derivatives, compounds
摘要 芦竹碱可以与智能和高效地供给Ñ,Ñ二甲氨基基团,然后与相应的磺酰氯反应,以合成Ñ,Ñ -dimethylarylsulfonamides。我们在本文中设计并控制了N,N-二甲基芳基磺酰胺衍生物的合成,并首先报道了15种标题化合物3a-o分别对体外隐孢子虫的杀线虫活性的结果。在所有标题衍生物中,化合物3a,3c,3k和3o表现出强大的杀线虫活性,致死浓度中位数(LC 50)值在0.22至0.26 mg / L的范围内。最值得注意的是,N,N-二甲基-4-甲氧基苯基磺酰胺(3c)和N,N-二甲基-8-喹啉磺酰胺(3o)表现出最有前途的杀线虫活性,LC 50值分别为0.2381和0.2259 mg / L。 。
