Dialdehyde-built disinsection activity-having nitrogen or oxygen-containing heterocyclic compound and preparation method

Abstract

The invention relates to the preparation and the use of a dialdehyde-built disinsection activity-having nitrogen or oxygen-containing heterocyclic compound, and provides a compound with a chemical formula showed as formula (A), (B), (C) or (D), or an optical isomer, a cis-trans isomer, or an agriculturally pharmaceutically acceptable salt of the compound,. The invention further relates to an agricultural composite which comprises the compound, or the optical isomer the cis-trans isomer of the compound, or the agriculturally pharmaceutically acceptable salt, the use of the agricultural composite, and a preparation method of the compound, or the optical isomer, the cis-trans isomer of the compound, or the agriculturally pharmaceutically acceptable salt. The compound and ramification thereof has high disinsection activity for agriculture and forestry injurious pests such as aphid, plant hopper, leafhopper, thrips palmi karny, cotton bollworm, cabbage caterpillar, plutella xylostella, prodenia litura and armyworm, etc.

Description

technical field

[0001] The invention relates to a novel neonicotinoid insecticide, a preparation method and application thereof. Background technique

[0002] Neonicotinoid insecticides represented by imidacloprid have high insecticidal activity, wide insecticidal spectrum, low toxicity to mammals and aquatic animals, good system properties, appropriate field stability and environmental friendliness, and become An important hot spot for the creation of new pesticides. A series of neonicotinoid insecticides such as thiacloprid, clothianidin, thiamethoxam, acetamiprid, nitenpyram, dinotefuran and the like have been developed successively afterwards (seeing European patents 247477, 296453, 685477, 235725, 235725, 315826, 192060, 244777, 0386565, 580553 and 1031566, Japanese patents 62292765, 8259568, 8291171 and 7242633).

[0003] However, due to the serious resistance problem caused by the excessive and frequent use of imidacloprid and the cross-resistance between neonicotin...
