The synthesis method of 5-amino-8-hydroxyquinoline has been explored by many scholars in the past. The first method is to use 8-hydroxyquinoline as the starting material, through nitrification reaction, introduce nitro groups, and then use the reduction method to convert nitro groups into amino groups, so as to obtain 5-amino-8-hydroxyquinoline. During nitrification, the reaction conditions, such as temperature and reagent ratio, need to be carefully selected, so that the nitro group can be accurately introduced into the 5-position. The reduction step is often done in an acidic medium such as iron powder and zinc powder, or by catalytic hydrogenation, select suitable catalysts, such as palladium carbon, etc., to control the reaction conditions to achieve good yield and purity.
Second, the quinoline skeleton can be constructed by condensation reaction of benzene and pyridine rings containing specific substituents, and then amino and hydroxyl groups can be introduced at an appropriate stage. For example, with suitable aniline derivatives and pyridine-2,3-dione derivatives, condensation under acidic or basic catalysis, followed by modification reaction, hydroxyl and amino groups are added to obtain the target product. The key to this approach lies in the optimization of condensation reaction conditions, and the selectivity and controllability of subsequent functional group introduction.
There are also quinoline compounds as substrates. After halogenation, halogen atoms are introduced at specific positions in the quinoline ring, followed by nucleophilic substitution reaction, halogen is replaced by amino group, and then hydroxylation is carried out. In this process, the selectivity of halogenation, the efficiency of nucleophilic substitution and the conditions of hydroxylation are all important factors affecting the formation of products. Each method has its own advantages and disadvantages, and it is necessary to weigh and choose according to actual needs and conditions in order to seek efficient synthesis of 5-amino-8-hydroxyquinoline.
