Заглавие : Cyclization of N-alkylazinium cations with bisnucleophiles. 3. endo adducts in the reaction of quinoxalium salts with β-diketones and their x-ray diffraction analysis Место публикации : Chemistry of Heterocyclic Compounds. - 1981. - Vol. 17, № 10. - С. 1046-1052 Примечания : Bibliogr. : p. 1052 (22 ref.) ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): n-alkylquinoxalinlum salts--β-dicarbonyl compounds--cycloadducts Аннотация: The cyclization of N-alkylquinoxalinium salts with the anions of β-dicarbonyl compounds proceeds regioselectively and stereoselectively and leads to endo-3a, 4,9,9a-tetrahydrofuro[2,3-b]quinoxalines. The structure of the cycloadducts was established on the basis of the 1H and 13C NMR spectra and the results of x-ray diffraction analysis Доп.точки доступа: Chupakhin, O. N.; Charushin, V.
