Abstract Indoles are a very important class of heterocyclic analogues, in various fields of medicine, pesticides, perfumes, dyes and the like is widely used。 In nature, indoles are widely distributed, but the actual production of direct extraction is very difficult, it is generally by chemical synthesis, so the indole synthesis studies are necessary and their derivatives。 This paper background indole analogues have been described, and the active indoles, especially medical activity and agricultural activity made a detailed presentation and discussion。 This article also describes various synthetic indole analogues to molecular skeleton Wintersweet base substrate occurs through different acylation anhydride or acid chloride synthesized a series of amide derivatives。 By the oxidation reaction, alkylation reaction, reduction and acylation range of semi-praecox base analogue for the subsequent synthesis of different substituted group types of analogues designed to discuss the evaluation of the antibacterial activity, structure-activity relationship and mechanism of action foundation。
