the limelight as a novel fungicide, and has fungicidal activity against Botrytis cinerea. For exploring more novel structures, 33 new compounds were synthesized by N-alkylation and acid-amine coupling reactions with chesulfamide as the core moiety, and their structures were characterized and established by ¹H-NMR, 13C-NMR, MS, and elemental analysis. The structure of (1R,2S)-2-(2-(N-(4-chloro-2-trifl
N-(2-三氟甲基-4-氯苯基)-2-氧代环己基磺酰胺(chesulfamide)作为新型杀菌剂备受瞩目,并且对灰葡萄孢具有杀真菌活性。为了探索更多新颖的结构,通过N-烷基化和以胺磺酰胺为核心部分的酸-胺偶联反应合成了33种新化合物,并通过1 H-NMR,13 C-NMR,MS和元素分析对它们的结构进行了表征和建立。(1R,2S)-2-(2-(N-(4-氯-2-三氟甲基苯基)氨磺酰基)-环己基氨基)-N-(2-三氟甲基苯基)乙酰胺(II-19)的结构由X-定义。射线单晶衍射。评价了对灰葡萄孢的体内和体外杀真菌活性。菌丝体生长的生物测定结果表明,大多数化合物在50μgmL-1的浓度下均对灰质芽孢杆菌具有优异的抑制活性,和7种化合物对灰质芽孢杆菌(CY-09)的EC50值均低于Boscalid(EC50 = 4.46μgmL-1)。在黄瓜盆栽试验中,四种化合物(II-4,II-5,II-12和
