Problems solved by technology

However, due to the thermodynamic stability and kinetic inertness of the pyridine ring, there are still great challenges in the process of deconstructing azaarenes into functional frameworks (Chen, X.W., Angew.Chem.Int.Ed.2017, 56, 14232-14236)

Abstract

The invention belongs to the technical field of pharmaceutical chemicals, and discloses an arylamine derivative synthesized by deconstructing an aza-aromatic hydrocarbon as well as a method and application thereof. The method comprises the following steps: 1) taking an organic solvent as a reaction medium, and reacting the aza-aromatic hydrocarbon with R-CH2-Br to obtain an aza-aromatic hydrocarbon brominated salt; and 2) in a protective atmosphere, in an organic solvent, carrying out a reaction on the aza-aromatic hydrocarbon brominated salt and an amino alcohol compound under the action of acatalyst or a catalyst and an accelerator, and carrying out subsequent treatment to obtain the arylamine derivative N-alkyl arylamine compound, the structure of which is shown in the specification. The method is safe, simple, low in raw material cost and beneficial to industrial production. The method for deconstructing and synthesizing the arylamine derivative from the aza-aromatic hydrocarbon,disclosed by the invention, is used for synthesizing a potent LXR agonist, a potent inhibitor of PSD95-nNOS protein-protein interaction and an Adaphostin (NSC 680410) analogue; the arylamine derivative is used for preparing a bedaquiline derivative.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical and chemical synthesis, and in particular relates to a method and application of deconstructing and synthesizing aromatic amine derivatives from azaarenes. Background technique [0002] Aromatic amine derivatives are a class of nitrogen-containing compounds with biological and pharmaceutical activities, which widely exist in alkaloids and synthetic drugs, and have a wide range of biological and pharmaceutical activities. For example, a potent LXR agonist, a potent inhibitor of PSD95-nNOS protein-protein interaction, and Adaphostin (NSC 680410) all contain aromatic amine backbone fragments (Lee, W.H., Neuropharmacology 2015, 97, 464–475; Kaur, G, Bioorg Med. Chem. 2005, 13, 1749–1761; Klisuric, O.R., Struct Chem 2016, 27, 947–960). In addition, aromatic amine compounds are also an important class of raw materials and intermediates, and have important uses in organic synthesis. Therefore, t...
