Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ISOQUINOLINE ALKALOIDS -- HETEROCYCLES -- ARYNE Аннотация: Reaction of 3-(pyridin-2-yl)-1,2,4-triazines with aryne intermediate, 4,5-dimethoxy-1,2-dehydrobenzene generated in situ, was investigated. As a result of the interaction products of the 1,2,4-triazine transformation are produced: 2,3-dimethoxy-10-(1H-1,2,3-triazol-1-yl)-pyrido[1,2-a]indoles, and also the products of Diels-Alder aza-reaction, 6,7-dimethoxy-1-(pyridin-2-yl)isoquinolines. \\\\expert2\\nbo\\Russian Journal of Organic Chemistry\\2015, 51, (8), 1170-1173.pdf |
