The synthesis method of 4-hydroxy-6-bromoquinoline-3-carboxylic acid ethyl ester is discussed in detail today.
First, it can be started from a compound containing a quinoline parent nucleus. Find a suitable quinoline derivative with a modifiable group in the appropriate position. For example, a quinoline compound has a functional group that can be converted into carboxyethyl ester at 3 positions, a check point that can be brominated at 6 positions, and a hydroxyl group can be introduced at 4 positions through a suitable reaction. First, the 6 positions are brominated, and a suitable brominated reagent is selected, such as liquid bromine, N-bromosuccinimide (NBS), etc. Taking NBS as an example, in an appropriate solvent, such as carbon tetrachloride and dichloromethane, in the presence of an initiator, such as benzoyl peroxide, heating or lighting, the bromine atom is selectively substituted to the 6 position. Then, the 3-position functional group is modified and subjected to a series of reactions, such as hydrolysis and esterification, to obtain the carboxylethyl ester structure. During hydrolysis, acid or base catalysis is selected according to the nature of the substrate. Alkaline solutions such as sodium hydroxide are commonly used for alkali catalysis, and sulfuric acid can be used for acid catalysis. During esterification, ethanol is used as an alcohol source, and ethyl 3-carboxylate is catalyzed by concentrated sulfuric acid or by the use of a condensing agent such as dicyclohexylcarbodiimide (DCC) and 4-dimethylaminopyridine (DM Finally, the hydroxyl group is introduced at the 4th position, which can be achieved by nucleophilic substitution, oxidation and other reactions according to the specific substrate structure.
Second, the quinoline ring can also be constructed from the construction of quinoline rings. Using suitable aniline derivatives and β-ketoacid esters as raw materials, the quinoline ring can be constructed by Pictet-Spengler reaction or similar cyclization reaction. During the reaction process, the raw material structure can be cleverly designed so that the cyclized quinoline product can be easily brominated at 6 positions, 3 positions have their own groups that can be converted into carboxyl ethyl esters, and 4 positions can be subsequently modified to introduce hydroxyl groups. Follow-up operations such as the above bromination, functional group conversion and other steps to obtain the target product 4-hydroxy-6-bromoquinoline-3-carboxylic acid ethyl ester.
The process of synthesis needs to be weighed according to many factors such as the availability of raw materials, the ease of control of reaction conditions and cost, and the optimal method can be selected to obtain it efficiently.
