followed by oxidation of peroxyacetic acid to afford their 6,7-epoxy analogues. All of the compounds were characterized by HR-ESI-MS and 1H-NMR spectral data. The preliminary bioassays showed that some of these compounds exhibited good fungicidal activities against Rhizoctonia solani (R. solani) at a concentration of 50 µg/mL. For example, 5C, 5I and 6b had 94.0%, 93.4% and 91.5% inhibition rates against R
为了寻找新的具有高杀菌活性的先导化合物,以市售香叶醇/橙花醇为原料,通过选择性两步氧化法合成了(Z/E)-3,7-二甲基-2,6-辛二烯酸。28 种不同的 (Z/E)-3,7-二甲基-2,6-辛二烯酰胺衍生物通过 (Z/E)-羧酸与各种芳香族和脂肪族胺反应制备,然后过氧乙酸氧化得到它们的 6,7-环氧类似物。所有化合物均通过 HR-ESI-MS 和 1H-NMR 光谱数据进行表征。初步生物测定表明,其中一些化合物在浓度为 50 µg/mL 时对立枯丝核菌(R. solani)表现出良好的杀真菌活性。例如,5C、5I 和 6b 分别对 R. solani 具有 94.0%、93.4% 和 91.5% 的抑制率。
