Suzuki, Toshinobu; Nagae, Yasushi; Mitsuhashi, Keiryo published the article 《Synthesis of pyrido[1′,2′:1,2]imidazo[4,5-b]pyrazines from 2,3-dichloro-5,6-dicyanopyrazine with 2-aminopyridines》. Keywords: chlorodicyanopyrazine cyclocondensation aminopyridine; pyridoimidazopyrazine.They researched the compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile( cas:56413-95-7 ).Recommanded Product: 5,6-Dichloropyrazine-2,3-dicarbonitrile. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:56413-95-7) here.
Novel synthesis of the title compounds I (R = H, 6-, 7-, 8-, 9-Me, 8-Cl, 8-Br, 6-PhCH2O) by the facile cyclization between 2,3-dichloro-5,6-dicyanopyrazine and various 2-aminopyridines II under relatively mild conditions is described. The reactivity depended on the basicity of 2-aminopyridines.
Although many compounds look similar to this compound(56413-95-7)Recommanded Product: 5,6-Dichloropyrazine-2,3-dicarbonitrile, numerous studies have shown that this compound(SMILES:N#CC1=NC(Cl)=C(Cl)N=C1C#N), has unique advantages.
