Abstract Series of thioether derivatives containing 4-methylumbelliferone fused oxazole moiety were designed and synthesised, their structures were fully characterized by 1H NMR, 13C NMR and HR-ESI-MS as well. Moreover, the in vitro antifungal potency of the title compounds were preliminarily evaluated for their possible use as a fungicide. Meanwhile, ethyl thioethers 3aa and 3ba displayed remarkable
摘要 设计合成了一系列含4-甲基伞形酮稠合恶唑的硫醚衍生物,并通过1 H NMR、13 C NMR和HR-ESI-MS对其结构进行了全面表征。此外,对标题化合物的体外抗真菌效力进行了初步评估,以确定它们可能用作杀真菌剂。同时,乙基硫醚3aa和3ba对Valsa mali和Botrytis cinerea的菌丝体生长具有显着的抑制作用,EC 50为 12-16 μg/mL。此外,化合物3aa和3ba在 90 μg/mL 的番茄果实上也表现出 > 88% 的对B. cinerea的保护和治疗作用。此外,还评估了标题化合物对盐水虾卤虫的环境毒性。结果表明,大多数标题化合物对水生生物A. salina 具有弱毒性。
