they are typically unstable to light or heat, difficult to extract and so on. To find highly potential fungicides derived from natural EOs, a series of essential oil-based β-methoxyacrylate derivatives have been designed and synthesized. The target compounds have been screened for their potential fungicidal activity against eleven species of plant pathogen fungi, including Alternaria alternata, Phomopsis

生物表现出明显更好的杀菌活性。进一步研究表明,与市售产品
嘧菌酯相比,一些化合物在不同浓度下对茶拟盘菌、拟茎点霉、核盘菌和稻瘟病菌表现出显着的抑制活性。化合物II-8表现出特别显着的杀菌活性。
