Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): N-METHYLQUINOXALINIUM IODIDE -- ETHYLENEDIAMINE -- O-AMINOPHENOL Аннотация: N-Methylquinoxalinium iodide reacts with ethylenediamine, o-phenylenediamine, and o-aminophenol to give cyclization products of the type involving [2,3-b] annelation of the six-membered heteroring. Two molecules of the quinoxaline participate in the cyclization with 2-aminoethanol to give a complex polycyclic compound. \\\\expert2\\nbo\\Chemistry of Heterocyclic Compounds\\1985, v.21, N 8, p. 933.pdf |
