Description

technical field

[0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a synthesis method of a cinnoline salt compound. Background technique

[0002] Quaternary ammonium salts are a class of widely used compounds that have drawn more and more attention because of their reactivity and biological activity. Among them, the cinnoline salt structure often appears in some biologically active compounds, drug molecules, alkaloids, receptors and inhibitors.

[0003] In the existing synthetic research of cinnoline salt compounds, the most commonly used method is to utilize the S of cinnoline and haloalkane N 2 reaction, but this method is not suitable for nitrogen-containing heterocyclic compounds that are very valuable.

[0004] Transition metal-catalyzed C–H functionalization and cross-coupling reactions have attracted extensive attention due to their advantages in atom economy and steps. Azobenzene is a widely used compound, which ...
