2-甲基-3-(4-对甲氧基苯基)-5-(3-甲氧基苯基)异噁唑啉及其生物活性

2-Methyl-3-(4-methoxyphenyl)-5-(3-methoxyphenyl)isoxazoline and Its Bioactivity

采用1,3-偶极环加成反应合成了2-甲基-3-对甲氧基苯基-5-间甲氧基苯基异噁唑啉,分离了顺、反异构体,采用核磁共振氢谱分析表征了顺反异构体的谱图行为,对异构体的生物活性进行了测定,新杀菌剂2-甲基-3-对甲氧基苯基-5-间甲氧基苯基异噁唑啉对病菌的有效成分为反式结构,顺式体为无效成分.

2-Methyl-3-（4-methoxyphenyl）-5-（3-methoxyphenyl）isoxazoline was synthesized by 1,3-dipo-lar cycloaddition,and the Z and E isomers were separated.1H NMR spectral analysis used to characterize the cis-and trans-isomers of the spectrum behavior.Their bioactivity shows that the E isomer is effective fungicide while Z isomer is ineffective.
