Abstract
Description
Technical Field
[0001] This invention relates to the field of organic compound technology, specifically to a meta-diamide compound and its application as a pesticide. Background Technology
[0002] In the production of agriculture, forestry, ornamental plants, and nursery crops, pests cause significant economic losses, and pesticides are widely used in agricultural production and planting. However, with the large-scale and prolonged use of pesticides, pests have developed resistance to many existing pesticides, requiring increased dosages to achieve the same effect, causing problems for agricultural production, the environment, and the ecosystem. For example, chlorantraniliprole is a highly effective pesticide for controlling the rice stem borer in rice cultivation; however, after years of continuous use, serious resistance problems have emerged in most parts of the world, posing a significant threat to global rice production. Therefore, there is a need for continuous research and development of new pesticides with high activity, rapid efficacy, low toxicity, and environmental friendliness. Summary of the Invention

[0061] This application enhances the lipophilicity of the m-diamid compound by selecting suitable groups for R1 and R2, and by the synergistic effect of suitable groups between R1 and R2. This makes it easier for pests to absorb the compound when applied in the insecticidal field, resulting in better insecticidal activity. Currently, commercially available m-diamid compounds produce their efficacy through demethylation in organisms, but pests develop resistance after long-term use. The m-diamid compound provided in this application produces its efficacy through deacylation in organisms. This type of m-diamid compound has not yet been used in the insecticidal field, and its application is less prone to resistance development. Furthermore, this application employs a special design to the structure of the m-diamid compound and the grafting positions of R1 and R2, such that the R1 group is attached to the C in C=W, and the C in C=W is grafted onto the N in the m-diamid compound that is attached to the carbonyl group. This reduces polarity, making it less likely for water molecules to form hydrogen bonds, thus reducing hydrophilicity and increasing lipophilicity. This results in the m-diamid compound exhibiting better lipophilicity, which can further enhance its insecticidal efficacy. This is because the modified structure has a faster enzyme metabolism rate in vivo, making it easier to produce efficacy more quickly through deacylation reactions in vivo.
[0062] The m-diamide compounds provided in this application do not exhibit cross-resistance with existing insecticides. Compared with existing insecticides on the market, these compounds have advantages such as rapid efficacy, low dosage, low toxicity, and environmental friendliness against plant pests.

[0388] The immersion method was used. After soaking the leaves of Chinese cabbage in the medicine for 10 seconds, they were placed in a plastic box lined with filter paper and allowed to air dry naturally. Ten third-instar diamondback moths were inoculated into each box. The boxes were placed in an observation room at 26℃ with 16 hours of light and 8 hours of darkness. The number of dead insects was observed after 3 days.

[0391]
[0392]
[0393] Note: Compound numbers correspond to those in Table 1.
[0394] The results show that the m-diamid compounds provided by this invention exhibit high bioactivity against both rice stem borer and diamondback moth, and these m-diamid compounds show no cross-resistance with chlorantraniliprole. Furthermore, a comparison of the embodiments of this application with CK01, CK02, CK03, and CK04 in Tables 2 and 3 shows that this application, through the selection of suitable groups for R1 and R2, and the synergistic effect of suitable groups between R1 and R2, can enhance the lipophilicity of the m-diamid compounds. When applied to the insecticidal field, these compounds are more easily absorbed by pests, thus exhibiting better insecticidal activity. In addition, this application, through a special design of the structure of the m-diamid compounds and the grafting positions of R1 and R2, makes the m-diamid compounds more lipophilic, which can further enhance their insecticidal efficacy. In pesticide organic small molecule compounds, due to differences in the type of substituents, group volume, and electronegativity, the metabolic and transport properties of the entire molecule in the organism can vary greatly, resulting in significant differences in biological activity. Furthermore, the metabolic properties, transport properties, and ability of the molecule to bind to receptors are unpredictable and require a great deal of creative work to determine.
[0395] The preferred embodiments have been described in detail above, but the present invention is not limited to the specific implementation methods described above. Those skilled in the art can make various specific modifications under the guidance of this application without departing from the scope of protection of this application, and these modifications all fall within the scope of protection of the present invention.
