Paragraph 0059-0061, (2017/10/07)
The invention discloses an N-substituted maleimide compound shown as a formula (I), a preparation method of the compound and application of the compound for inhibiting riziocotinia solani or sclerotinia sclerotiorum. The preparation method comprises the following steps: taking anhydride shown as a formula (II) and organic amines as raw materials, dissolving the raw materials in a solvent acetone, magnetically stirring, completely reacting at room temperature, performing rotary evaporation to remove the solvent acetone, adding methylbenzene to serve as a solvent, carrying out an amidation reaction and a closed-loop dehydration reaction under the actions of stabilizers and a dehydrating agent, separating and purifying the reaction solution after the reaction is ended, thereby obtaining the N-substituted maleimide compound shown as the formula (I). The organic amines refer to chlorobenzylamine, ethanol amine, propanolamine, aminophenol or (R)-(+)-1-(4-metoxybenzene) ethylamine; the stabilizers comprise hydroquinone and anhydrous sodium acetate; the dehydrating agent is triethylamine. The N-substituted maleimide compound disclosed by the invention is simple in preparation method and convenient to operate and has excellent effects on rice sheath blight disease and sclerotinia stem rot. The structural formula is as shown in the specification.
