On November 30, 1989, Volovenko, Yu. M.; Litvinenko, S. V.; Babichev, F. S. published an article.Computed Properties of 58142-46-4 The title of the article was Annulation of benzoindolizine rings to quinoxaline nucleus. And the article contained the following:
Quinoxalineacetonitriles I (R3 = Me, Ph, or 4-MeC6H4) react with isoquinolines II (R1 = H, R2 = H, NO2; R1 = Br, R2 = NO2) 2-4 h in DMF at 160° or reflux to give quant. benzindolizinoquinoxalines III. The experimental process involved the reaction of 4-Bromo-5-nitroisoquinoline(cas: 58142-46-4).Computed Properties of 58142-46-4
The Article related to benzindolizinoquinoxalinecarbonitrile, indolizinoquinoxaline benz, quinoxaline benzindolizino, isoquinoline quinoxalineacetonitrile reaction, Heterocyclic Compounds (More Than One Hetero Atom): Pyrazines and Quinoxalines (Including Piperazines) and other aspects.Computed Properties of 58142-46-4
