- Synthesis, Antifungal Activity, and SAR Study of Some New 6-Perfluoropropanyl Quinoline Derivatives
-
A series of novel quinoline derivatives containing perfluoropropanyl moiety were designed and synthesized. The bioassay results showed that some of them exhibited good control efficacy against Pyricularia oryae. The fungicidal activity was affected by the substituted position in the molecule. It was found that the compound 3n possessed highest control effect against P.?oryae at different concentration. It is better than that of control Tebufloquin.

- Synthesis and fungicidal activities of perfluoropropan-2-yl-based novel quinoline derivatives
-
A series of novel perfluoropropan-2-yl-based quinoline derivatives was designed and synthesized utilizing tebufloquin as the lead compound. The structures of all the newly synthesized compounds were confirmed by spectroscopic data 1HNMR, MS and elemental analysis. The results of bioassay indicated that these compounds exhibited potent fungicidal activities against Erysiphe graminis. Especially, compound 8c displayed excellent activity with EC50 value at 1.48 mg / L, which was better than that of the commercialized fungicide-tebufloquin. The structure-activity relationship for these new compounds was also discussed.
