Luger, Peter et al. published their research in Helvetica Chimica Acta in 1977 | CAS: 5448-43-1

6-Chloroquinoxaline (cas: 5448-43-1) belongs to quinoxaline derivatives. Condensed heterocycles of quinoxalines have become attractive targets in synthetic and medicinal chemistry due to their significant biological activities. Quinoxalines are used in the treatment of bacterial, cancer, and HIV infections. Moreover, varenicline, a clinical drug is used for treating nicotine addiction, also contains quinoxaline moiety.Application of 5448-43-1

Macrocyclic aza compounds. IV. Synthesis and x-ray analysis of 2-(2-2H-benzotriazolyl)-N-(6-quinoxalinyl)aniline, the rearrangement product from 1,2-bis(2-aminophenylazo)benzene and glyoxal was written by Luger, Peter;Malkowski, Jerzy;Skrabal, Peter. And the article was included in Helvetica Chimica Acta in 1977.Application of 5448-43-1 This article mentions the following:

The title compound (I) was prepared in 3% yield by treating 6-chloroquinoxaline with 2-(2-aminophenyl)-2H-benzotriazole in the presence of Cu-K2CO3. X-ray anal. showed that I is identical with the condensation product of o-C6H4(N:NC6H4NH2-o)2 and glyoxal. In the experiment, the researchers used many compounds, for example, 6-Chloroquinoxaline (cas: 5448-43-1Application of 5448-43-1).
