Abstract

The invention provides preparation of a pyrrole and pyrrolin fused ring compound with insecticidal activity and use of the pyrrole and pyrrolin fused ring compound with insecticidal activity. Specifically, the invention relates to a compound (shown as the following formula) with the general formula (A) or the optical isomer, the cis-trans-isomer or the agriculturally pharmaceutically acceptable salt of the compounds, and a preparation method of the compound. The invention further relates to an agricultural composite containing the compound, or the optical isomer, the cis-trans-isomer or the agriculturally pharmaceutically acceptable salt of the compound and the use of the agricultural composite. The compound and the derivative of the compound are high in insecticidal activity to agriculture and forestry pests with the same mecoptera, lepidoptera and the like such as the aphid, the plant hopper, the aleyrodid, the leafhopper, the thrips, the cotton bollworm, the cabbage caterpillar, the plutella xylostella, the prodenia litura, the armyworm and the like.

Description

technical field

[0001] The invention relates to the field of pesticides, in particular to a preparation method and application of pyrrole and dihydropyrrole fused-ring neonicotinoid pesticides. technical background

[0002] The alkaloid nicotine from tobacco leaf extract is a natural insecticide that acts on postsynaptic nicotinic acetylcholine receptors (nAChRs). For a long time, researchers have been using natural nicotine as the leading compound to find and discover new compounds with insecticidal activity that are similar in structure to nicotine and have the same mechanism of action. In the mid-1980s, Bayer developed the first neonicotinoid insecticide, imidacloprid, and became one of the most successful new insecticides. High activity, wide insecticidal spectrum, low toxicity to mammals and aquatic animals, good system properties, appropriate field stability and environmental friendliness have become an important hotspot for the creation of new pesticides. Later, a s...
