A series of N-(4-(N′-substituted sulfamoyl)phenyl)myrtenamides containing a heterocycle were designed and synthesized by a multiple-step procedure using α-pinene as starting material. All the synthesized compounds were characterized and analyzed by GC, HPLC, UV-vis, FTIR, NMR, GC-MS, and ESI-MS. The preliminary bioassay showed that, at 50 μg/mL, the target compounds exhibited a certain antifungal activity against the five tested fungi, in which compound 5f exhibited antifungal activity of 83.2% and 70.0% against Physalospora piricola and Alternaria solani, respectively. Moreover, compound 5d displayed herbicidal activity of 86.0% against the root of rape (Brassica campestris) at 100 μg/mL.
以α-蒎烯为起始原料,通过多步法设计和合成了一系列含有杂环的N-(4-(N′-取代的氨基磺酰基)苯基)肉桂酰胺类化合物。所有合成化合物均通过气相色谱、高效液相色谱、紫外可见光、傅立叶变换红外光谱、核磁共振、气相色谱-质谱和电喷雾质谱进行了表征和分析。初步生物测定表明,在 50 μg/mL 的浓度下,目标化合物对五种受试真菌具有一定的抗真菌活性,其中化合物 5f 对 piricola Physalospora 和 Alternaria solani 的抗真菌活性分别为 83.2% 和 70.0%。此外,化合物 5d 在 100 μg/mL 的浓度下对油菜(Brassica campestris)根部的除草活性为 86.0%。
