Description

technical field

[0001] The invention relates to a class of arylpropenone compounds containing 1,3,5-oxadiazine heterocycle, a preparation method thereof and the application of the compounds in preventing and controlling agricultural pests. Background technique

[0002] Stellera chamaejasme (Stellera chamaejasme L.) is a plant of the genus Stellera chamaejasme. A long time ago, people discovered that the root of Stellera chamaejasme can be used to make biological pesticides—plant insecticides, which have the functions of contact killing, stomach poisoning, and fumigation. It can effectively control cabbage caterpillar, aphid, soybean borer, cotton red spider, night thief, pine moth, pine caterpillar, pine sawfly, etc., but the active ingredients are not clear, and the research mainly focuses on ethanol extract. In 2001, people such as Liu Shigui extracted daphnetin with n-hexane for the first time, and isolated two kinds of active compounds (E)-1,5-diphenyl-2-ene-1-pentanone ...
