Chupakhin // Journal of Organic Chemistry. - 2012. - Vol.77, №14. - С. 6007-6013 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CYCLIC KETONES -- TRIAZINE -- KETONES Аннотация: Reactions between substituted 1,2,4-triazines and ketones were investigated. General procedures for one-pot synthesis of hydrogenated derivatives of such polycyclic systems as benzo[c][1,2,4]triazino[1,6-a][2]azecine, [1,2,4]triazino[1,6-f]phenantridine, and dicyclopenta[b,d]pyrido[1,2-f][1,2,4]triazine are described \\\\Expert2\\nbo\\Journal of Organic Chemistry\\2010, v.77, p.6007.pdf |
