Saloutin // AIP conference proceedings. - 2022. - Vol. 2390. - Ст. 020021 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): TRIFLUOROACETOACETATE -- METHYL KETONES -- DIAMINES Аннотация: The three-component cyclization of ethyl trifluoroacetoacetate and 2-aminoethanol with 3-methyl-2-butanone in hexahydrooxazolo[3,2-a]pyridin-5-ones was studied. The reaction leads to a mixture of cis- and trans- diastereomers, the structures of which were investigated using 1H, 19F, 13C NMR spectroscopy. |
