Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a spiro indolinone compound, and a preparation method and application thereof. According to the preparation method, a dispiro[benzofuranone-2,3'- pyrrolidone-2',3''-indolinone] compound is obtained by dissolving an N-substituted indigo derivative, alpha-amino acid and an aurone derivative in an organic solventaccording to a certain proportion in a one-pot synthesizing mode, removing the organic solvent after a TLC detection reaction is ended and recrystallizing; and the preparation method is simple. The dispiro[benzofuranone-2,3'- pyrrolidone-2',3''-indolinone] compound disclosed by the invention shows good activity to plant virus, and particularly has a very good prevention and treatment effect on preventing and treating tobacco mosaic virus.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a spirocyclic indolinone compound and a preparation method and application thereof. Background technique [0002] Spiro compounds have a wide range of physiological and pharmacological activities, and exist in large quantities in drugs and natural alkaloids. Orange ketone, 2-phenylmethylene-3-(2H)-benzofuranone, is a secondary metabolite in plants, not only participates in the process of plant growth and reproduction, gives plants yellow or orange color, but also benefits plants Defense against pathogens and pests and inhibiting the growth of competitive weeds. Orange ketone contains active extracyclic double bonds, which can undergo cycloaddition reaction with 1,3-dipole to construct spiro compounds containing benzofuranone, but there is a lack of related research results in the prior art, and benzofuranone The application of the spiro compound of furanone in an...
