The common synthesis methods of methyl 6-chloro-5-nitropyridine-3-carboxylic acid esters cover the following kinds.
First, the corresponding pyridine derivative is used as the starting material. If the pyridine is taken first, the chlorine atom, nitro group and carboxyl methyl ester group are introduced at a specific position through a specific reaction. This process may involve an electrophilic substitution reaction. Because the pyridine ring has a certain electron cloud density distribution, it can make it easier to interact with the electrophilic reagent at a specific position. For example, the chlorine atom on the pyridine ring can be introduced by using a chlorine-containing electrophilic reagent under suitable catalyst and reaction conditions, and then the nitro group and carboxyl methyl ester group can be introduced sequentially through a similar method. However, this path requires fine regulation of the reaction conditions. Due to the different reactivity at different positions on the pyridine ring, slight carelessness or side reactions may occur, which affects the yield and purity of the target product.
Second, the strategy of constructing the pyridine ring is adopted. That is, the pyridine ring is first constructed by cyclization reaction based on non-pyridine compounds, and the structural unit of 6-chloro-5-nitro-3-carboxylic acid methyl ester is introduced at the appropriate step. In this approach, the cyclization reaction is a key step, and the appropriate reactants and reaction conditions need to be selected to promote the formation of the pyridine ring structure in the molecule. For example, through specific condensation and cyclization reactions, molecules are gradually formed into pyridine rings, and the positions of substituents are precisely positioned. Although this method may be cumbersome, it is a feasible method for situations where specific raw materials are abundant or have special requirements for reaction selectivity.
Third, the reaction catalyzed by transition metals. Transition metal catalysts can effectively promote the formation and fracture of various chemical bonds and can be used in the synthesis of this compound. For example, the use of transition metal catalysts such as palladium and copper catalyzes the reaction of halogenated aromatics with reagents such as nitrogen and carboxyl groups to achieve the construction of pyridine rings and the introduction of substituents. This method usually has high reactivity and selectivity, and can be carried out under relatively mild conditions, but the catalyst cost is higher, and the purity and operation requirements of the reaction system are also stricter.
