For the first time, a novel series of tschimganin analogs were designed, synthesized, and evaluated for their insecticidal and fungicidal activities. Their structures were characterized by ¹H-NMR, C-NMR and HRMS. Some of these compounds displayed excellent insecticidal and fungicidal activities, suggesting that they have potential to be used as bifunctional agrochemicals. Compound and with electron donating groups showed better inhibitory activity and growth inhibition activity towards (Hübner). The properties and positions of the substituents on the benzene ring have an important influence on the acaricidal activity of tschimganin analogs. Topomer comparative molecular field analysis (CoMFA) was employed to develop a three-dimensional quantitative structure-activity relationship model for the compounds against Ugarov et Nikolski. It was indicated that higher electronegativity was beneficial for acaricidal activity. Moreover, compound having a 2-hydroxy-3,5- dinitrophenyl moiety displayed a fungicidal spectrum as broad as azoxystrobin against these phytopathogens.
