Заглавие : Conditions for the Synthesis of 4,5-Diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles by the Reaction of 1,2,4-Triazine-5-carbonitriles with 2-Aminooxazoles Место публикации : Russian Journal of Organic Chemistry. - 2022. - Vol. 58, № 2. - С. 175-179 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Various conditions for the inverse electron-demand aza-Diels–Alder reaction in the series of 5-aryl-3-(2-pyridyl)-1,2,4-triazine-5-carbonitriles and 2-amino-4-aryloxazoles to obtain 4,5-diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles were tested. Heating in 1,2-dichlorobenzene or under solvent-free conditions were found to be the most effective. Доп.точки доступа: Rammohan, A.; Krinochkin, A. P.; Kopchuk, D. S.; Shtaitz, Y. K.; Kovalev, I.
