The chemical synthesis of 3-cyano-7-ethoxy-4-hydroxy-6- (acetamido) quinoline requires multiple steps of delicate reactions. First, suitable quinoline derivatives are often used as starting materials. Or take quinoline with appropriate substituents, such as those with modifiable groups at specific positions.
The introduction of ethoxy groups can be used to obtain 7-ethoxy quinoline derivatives by nucleophilic substitution reaction of quinoline substrates with ethoxylating reagents, such as sodium ethanol and corresponding halogenated hydrocarbons, in suitable solvents. This reaction requires attention to the control of reaction temperature and time. If the temperature is too high or side reactions occur, if the time is too short, the reaction will not be fully functional.
times and 4-hydroxyl groups are added. Or by hydrolysis, oxidation and other reactions, a specific group is converted into a hydroxyl group. For example, if the starting material has a hydrolyzable ester group or an oxidizable group, it is treated under the corresponding conditions to form a hydroxyl group at the 4 position. During hydrolysis, suitable acid and base conditions need to be selected. If the acid and base are too strong or damage other parts of the molecule.
As for the construction of 6 - (acetamide), the amino group is often introduced first with an amination reagent and then reacted with an acetylation reagent. For example, ammonia gas or ammonia derivatives react with substrates to form aminoquinoline, and then react with acetyl chloride or acetic anhydride under the catalysis of an appropriate base to form a 6- (acetamido) structure. In this process, the amount and activity of the base are also key, which are related to the selectivity and yield of the reaction.
The formation of 3-cyano groups can be reacted with cyanide reagents by halogenated compounds. The 3-halogenated quinoline derivatives react with cyanidating agents such as potassium cyanide or sodium cyanide in an organic solvent in the presence of a phase transfer catalyst to obtain a 3-cyano product. The choice and amount of phase transfer catalyst have a great impact on the reaction rate and efficiency.
