Abstract

The reaction of ethyl aminocrotonates with derivatives of malonic acid is a suitable method for the preparation of ethyl 4-hydroxy-6-methyl-2-oxo-1,2-dihydropyridine-5-carboxylates. One of the synthesized materials has been studied by X-ray crystallography. ... Keywords: 4-hydroxy-2-oxopyridinecarboxylic acids, 1,2-dihydropyridin-2-ones, ethyl 3- aminocrotonic acids, X-ray crystallography. ... 6-Alkyl-substituted 1,2-dihydropyridin-2-ones are used in ...
