There are several common methods for the synthesis of 7-azaindolo [3,2-b] pyridine:
First, a suitable compound containing nitrogen and pyridine structure is used as the starting material, and the target skeleton is constructed by condensation reaction. For example, select aniline derivatives and pyridinal compounds with specific substituents, and the condensation reaction occurs under the catalysis of acid or base. During the reaction, the acid can promote the nucleophilic addition and dehydration steps, while the base can adjust the electron cloud density of the reaction system, promoting the reaction to proceed in the direction of generating the target product. The key to this method lies in the selection of starting materials and the precise regulation of reaction conditions, so that the condensation reaction occurs efficiently and selectively.
Second, it is prepared by the cyclization reaction catalyzed by transition metals. Transition metal catalysts such as palladium and copper are often used with appropriate ligands. For example, halogenated pyridine derivatives and nitrogenous alkynes are used as raw materials. Under the action of palladium catalysts and ligands, the metallization of alkynes occurs first, and then the nucleophilic substitution reaction occurs with halogenated pyridine, and then the cyclization forms 7-azaindolo [3,2-b] pyridine structure. The advantage of this method is that the reaction conditions are relatively mild, and the reaction selectivity can be regulated by changing the ligand. However, the cost of transition metal catalysts is higher, and the post-processing may be more complicated.
Third, the intramolecular rearrangement reaction is used. The azapropane derivative with a specific structure is used as the precursor, and the intramolecular rearrangement occurs under heating or light conditions. In this process, the azapropane ring is opened and recombined to construct the core structure of 7-azaindolo [3,2-b] pyridine. This method has high atomic economy and does not require additional complex reagents. However, the synthesis of the precursor compound requires high requirements, and its structure needs to be precisely designed to ensure the smooth progress of the rearrangement reaction.
