Заглавие : 2-Aminooxazoles as novel dienophiles in the inverse demand Diels–Alder reaction with 1,2,4-triazines Место публикации : Mendeleev Communications. - 2021. - Vol. 31, № 4. - С. 542-544 ББК : Г Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): 1,2,4-triazines--oxazol-2-amines--diels–alder reaction--2,2'-bipyridin-3-ols Аннотация: High temperature coupling of 6-aryl-5-cyano-3-(pyridin-2-yl)-1,2,4-triazines with 2-amino-4-aryloxazoles proceeds as the inverse demand Diels–Alder reaction between the oxazole moiety as dienophile and the 1,2,4-triazine moiety as diene to construct new 4,5-diaryl-6-cyano-3-hydroxypyridin-2-yl fragment. A reaction mechanism is proposed, and the structure of the key-product is proved by the X-ray diffraction analysis. Доп.точки доступа: Krinochkin, A. P.; Mallikarjuna Reddy, G.; Kopchuk, D.
