Abstract

The invention discloses an N-substituted benzenesulfonyl-3-propionyl indole derivative, a preparation method and application and belongs to the technical field of organic synthesis. The structural formula of the N-substituted benzenesulfonyl-3-propionyl indole derivative is shown in a formula II which is shown in the description. In the formula II, R1 is selected from H, 6-Me or 5-CN; R2 is selected from p-Me, p-Et, m-NO2, p-Cl or p-OMe. The compound is prepared by sulfonylation in nitrogen site and propionylation in C-3 site by taking substituted indole as a raw material. The derivative shows good bacteriostatic activity to 15 plant pathogenic fungi and can be used for preparing a plant pathogenic fungi bacteriostatic agent.

Description

technical field [0001] The invention relates to a kind of N-substituted benzenesulfonyl-3-propionyl indole derivatives, and also relates to the preparation method and application of N-substituted benzenesulfonyl-3-propionyl indole derivatives, belonging to organic synthesis technology field. Background technique [0002] Indole compounds have various biological activities such as anti-inflammation, anti-tumor, anti-bacteria, anti-virus, anti-HIV, etc. In recent years, they have achieved satisfactory clinical effects, and have attracted more and more attention from chemical researchers all over the world. In-depth synthesis of a series of biologically active compounds.
