In order to find novel and environmental friendly insecticides targeting the ryanodine receptor, three series of novel phthalamides containing heptafluoroisopropyl group, low fluorine atoms group and non-fluorine group were designed and synthesized. 35 novel structures of three series were obtained. Insecticidal activities of title compounds against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella) indicated that most of title compounds showed moderate to high activities at the tested concentration. The structure-activity relationship (SAR) was discussed in detail. During synthesizing title compounds B8, C7, D1, D9 and D12, their corresponding positional isomers (B8′, C7′, D1′, D9′ and D12′) were afforded, and their structures were confirmed by 2D NMR. The calcium-imaging technique was also applied to investigate the effects of compounds B2, B10, C4 and C5 on the intracellular calcium ion concentration ([Ca2+]i), which indicated that they released stored calcium ions from endoplasmic reticulum, which denoted that some compounds are potential modulators of the insect ryanodine receptor (RyR).

The present invention provides an aniline derivative represented by the formula (I) wherein R1 and R2 are each H, (C1-12)alkyl, (C3-8)cycloalkyl, hydroxy(C1-12)alkyl, hydroxycarbonyl (C1-12)alkyl, (C1-6)-alkoxycarbonyl(C1-6)alkyl, —COR8, wherein R8 is H, halo-(C1-12)alkyl, (C3-8)cycloalkyl or (substituted) phenyl, COOR9, wherein R9 is a halo(C1-6)alkyl group, (substituted) phenyl or (substituted) benzyl; R3, R4, R5, R6and R7 are each H, halogen, OH, nitro, halo(C1-12)alkylthio, (substituted)amino-(C1-2)alkyl, (substituted) phenyl, (substituted) benzyl, amino, —N(R10)R11 wherein R10 and R11 are each H, alkyl, cycloalkyl, (substituted) phenyl, (substituted) benzyl, —COR8 or COOR9, or (C2-27)perfluoroalkyl, etc., and a process for producing the aniline derivative. According to the process of the present invention, perfluoroalkylaniline derivatives can be obtained by using various anilines as the substrate with a high position selectivity and high yield.
