Study of heterocyclic quinones. XXVII. Catalysis by copper ions of the reaction of quinoxaline-5,8-quinones with amines was written by Chernyak, S. A.;Tsizin, Yu. S.. And the article was included in Khimiya Geterotsiklicheskikh Soedinenii in 1976.Product Details of 6639-82-3 This article mentions the following:
Aminomethoxyquinoxaline I, prepared in 71% yield from nitroaminoanisole and N2H4.H2O by cyclization, nitration, and reduction, was oxidized by ·ON(SO3K)2 to give 65% II (R1 = OMe, R2 = H) which was aminated by morpholine and piperidine to give 86 and 78% II (R1 = morpholino, piperidino, R2 = H), resp. Addnl. obtained were 65-83% II (R1 = R2 = morpholino, piperidino; R1 = piperidino, R2 = morpholino) and 95% CuCl2 complex of II (R1 = piperidino, R2 = H). In the experiment, the researchers used many compounds, for example, 6-Methoxyquinoxaline (cas: 6639-82-3Product Details of 6639-82-3).
6-Methoxyquinoxaline (cas: 6639-82-3) belongs to quinoxaline derivatives. Quinoxaline derivatives are important constituents of pharmacologically active compounds, including as well as for RNA synthesis inhibition, reactive dyes and pigments, azo dyes, flurox Cylin Dyes, Corrosion Inhibitors and Photovoltaic Polymers. Quinoxalines are used as dyes, pharmaceuticals, and antibiotics such as echinomycin, levomycin exhibiting antitumoral properties. Quinoxalines establish also the basis of anthelmintics and receptor antagonists.Product Details of 6639-82-3
