Заглавие : New opportunities for the synthesis of quinoxaline-substituted heterocyclic and aryl moieties [Электронный ресурс] Место публикации : Pharmaceutical Chemistry Journal. - 2013. - Vol.47, №9. - С. 498-502 Систем. требования: http://download.springer.com/static/pdf/597/art%253A10.1007%252Fs11094-013-0989-z.pdf?auth66=1395993119_3f641570d86d194b43c2c6e0beb1d0e5&ext=.pdf Примечания : Bibliogr. : p. 502 (10 ref.). - 26.03.2014 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): dimedone--indandione--dmso solution Аннотация: 6.7-Difluoroquinoxaline (I) reacted with dimedone, indandione, and 3-methyl-1-phenylpyrazol-5-one in DMSO solution in the presence of acid to form mono-substituted products IIa - c. Heating I with resorcinol in EtOH in the presence of acid gave resorcinol derivative IId. 6.7-Difluoroquinoxaline in the presence of base reacted with 3-methyl-1-phenylmethylpyrazol-5-one to form dipyrazolylmethane III and tetrapyrazolylethane derivative IV. Heating products IIa - c with N-methylpiperazine produced 7-methylpiperazine derivatives Va - c of 2-substituted quinoxalines Доп.точки доступа: Azev, Y. A.; Kodess, M.
