摘要： To discover new strobilurin analogs with high pesticidal activity, 11 novel methoxy acrylates bearing biaryl methanone oxime ether moieties were synthesized from aroyl pyridines, and characterized by H-1 and C-13 NMR and HRMS. In vitro fungicidal evaluation indicated that all of the target compounds exhibited excellent activities against tested seven phytopathogenic fungi, and compounds 5d and 5g displayed comparable overall activities to azoxystrobin and trifloxystrobin. Some of the target compounds also exhibited excellent in vivo control effects at 400 mg/L, for example, compound 5h could 100% control wheat powdery mildew and cucumber anthracnose. Furthermore, at 25 mg/L, these compounds, including control agents, completely inhibited spores germination of rice blast, but no effect at all for cucumber gray mold. These results suggested that this class of compounds might deserve to be developed as new potential agricultural fungicides.
