Embodiment 1

[0042] The compounds of the present invention are generally prepared by the following methods:

[0043] (1) In a three-necked flask equipped with a thermometer, condenser tube and electric magnetic stirrer, put 0.50mol quercetin, 0.020mol p-toluenesulfonic acid and 300mL anhydrous methanol, fully stir, react overnight at reflux temperature, remove Solvent, the concentrated solution was dissolved in toluene, washed, dried over anhydrous magnesium sulfate, and precipitated to obtain a yellow oily liquid with a crude product yield of 86%, which was directly used in the next step without purification.

[0044] (2) Add 30 mmol of the product of step (1), 50 mmol of phosphorus pentasulfide, and 100 milliliters of pyridine in a three-necked flask, reflux reaction, follow the reaction by TLC until the end of the reaction, cool, add 50 milliliters of purified water, stir, and generate a precipitate. A yellow solid was obtained by suction filtration. The yellow solid was dissolved in 20...

Description

technical field [0001] The invention relates to the field of novel compounds and pesticide compositions containing the compounds, in particular to a compound for preventing and treating kiwi fruit soft rot and derivatives thereof. Background technique [0002] In recent years, large-scale outbreaks of virus diseases in China's food crops, cash crops, and vegetables and fruits, as well as the lack of effective antiviral agents have led to disasters in virus diseases, and food virus diseases are spreading in the world pattern of "China-Southeast Asia-East Asia". Agricultural virus damage has become the bottleneck and obstacle affecting the normal and orderly development of my country's agriculture and the world's agriculture. How to quickly and effectively obtain high-efficiency and low-cost green anti-virus disease pesticides has become the focus of current agricultural science. Virus diseases of rice, corn and vegetables caused by rice stripe virus, rice dwarf virus, corn rou...
