To prepare 2-chloro-4,6-dimethyl-3-pyridinecarboxylic acid, there are several common synthesis methods.
First, the corresponding pyridine derivative can be used as the starting material. First, take a suitable 2-position pyridine compound containing a free-leaving group and 4,6-dimethyl, and react with a chlorine-containing reagent under suitable conditions to introduce the 2-position into the chlorine atom. This chlorine-containing reagent, such as thionyl chloride and phosphorus oxychloride, undergoes a substitution reaction in a suitable solvent, such as dichloromethane, chloroform, etc., under heating or in the presence of a catalyst, to obtain a 2-chloro-4,6-dimethylpyridine intermediate. Then, the intermediate is oxidized with a suitable oxidant, such as potassium permanganate, potassium dichromate, etc. in an acidic medium, and the methyl group on the pyridine ring is oxidized to a carboxyl group, so as to obtain the target product 2-chloro-4,6-dimethyl-3-pyridine carboxylic acid.
Second, a strategy for constructing a pyridine ring. Use small molecule compounds containing appropriate substituents to construct a pyridine ring through a condensation reaction. For example, select methyl-containing β-ketoacid esters and chloronitrile-containing compounds, and under the action of basic catalysts such as sodium alcohol, through a multi-step cyclization reaction, first form a pyridine ring, and introduce methyl and chlorine atoms at the same time. Subsequently, the obtained pyridine product is suitably modified, such as hydrolysis, acidification and other steps, so that the ester group is converted into a carboxylic group, and finally 2-chloro-4,6-dimethyl-3-pyridinecarboxylic acid.
Third, biosynthesis can also be used. Screen specific microorganisms or enzymes, use their catalytic properties, and use suitable substrates as raw materials to achieve the synthesis of the target product in a mild organism or in a simulated organism environment. This method has mild conditions and high selectivity, but has high requirements for the screening and culture of biological systems.
