A series of original pyrimidinamine derivatives containing a biphenyl ether moiety were designed and synthesized. Their structures were confirmed by 1H NMR, MS, and elemental analyses. Their insecticidal activities against lepidopteran and hemiptera insects and acaricidal activities were tested. The results of bioassay demonstrated that 9k showed the best activity (LC50 = 2.08 mg/L) against Tetranychus urticae, which is comparable with the positive control, spirotetramat (LC50 = 2.27 mg/L), and 9g showed better activity (LC50 = 0.52 mg/L) against Aphis fabae than the positive control, imidacloprid (LC50 = 1.02 mg/L), and relatively good activity (LC50 = 2.49 mg/L) against T urticae. Their structure-activity relationships indicated that both an ethyl group on the 4-position of the pyrimidine ring and alkyl chain as a para-substituent group of the benzene ring showed good biological activity.

Rusts are one of the most important fungal diseases, the known target sites have already developed serious resistance to the main existing classifications of fungicides. In order to discover novel fungicides with a promising activity on rusts, twenty new substituted difluoromethylpyrimidinamine derivatives were designed and synthesized with the aid of the intermediate derivatization methods starting from ethyl 4,4-difluoro-3-oxobutanoate that is the common raw material in some newly launched important succinate dehydrogenase inhibitor (SDHI) fungicides. Their structures were identified by 1H NMR, 13C NMR, 19F NMR, IR, elemental analyses and HRMS. All the compounds were screened for in vivo fungicidal activity against southern corn rust (SCR). The preliminary bioassay results indicated that 5-chloro-6-(difluoromethyl)-N-(2-(6-(3-(trifluoromethyl)phenoxy)pyridin-3-yl)ethyl)pyrimidin-4-amine (compound J, R1 = CHF2, Alk = CH2CH2, Rn = 3-CF3) is the optimal structure with desired fungicidal activity against SCR (EC50 = 2.16 mg/L), significantly higher than commercial fungicides diflumetorim (EC50 = 53.26 mg/L) and propiconazole (EC50 = 3.92 mg/L). The structure–activity relationship of the synthesized compounds was discussed as well. This study also demonstrated that difluoromethylpyrimidinamine derivatives can be further utilized as a promising antifungal agent to control rust. Further synthesis and structure optimization studies are currently in progress.
