characterized by 1H NMR, 13C NMR, and HRMS. The fungicidal activities of these novel compounds against Fusarium oxysporum, Magnaporthe grisea, Botrytis cinerea, and Penicillium digitatum were evaluated. The results indicated that (1S,2R,4S)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl(Z)-4-oxo-4-(((2-phenylthiazol-4-yl)methyl)amino)but-2-enoate (6a) displayed potential fungicidal activities with broad spectrum.

设计、合成了一系列含有 2-芳基-噻唑支架的 (-)-冰片衍生物,并通过1 H NMR、13 C NMR 和 HRMS 对其进行了表征。评价了这些新型化合物对尖孢镰刀菌、灰霉病菌、灰葡萄孢菌和指状青霉病菌的杀真菌活性。结果表明(1S,2R,4S)-1,7,7-三甲基双环[2.2.1]庚烷-2-基(Z)-4-氧代-4-(((2-苯基噻唑-4-基)甲基)氨基)but-2-enoate ( 6a)显示出广谱的潜在杀菌活性。特别是,6a展示了 IC 50对 P. digitatum 的值为 48.5 mg/L,其杀菌活性高于商品 hymexazol 和 amicarthiazol。此外,(1S,2R,4S)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl-4-oxo-4-(((2-phenylthiazol-4-yl)methyl)amino)butanoate (
