Abstract
The hydrogenation of 4-(2-furyl)-2-oxobutenoic acid sodium salt on a nickel catalyst has been studied. Using Raney nickel catalyst, the corresponding salts of 4-(2-furyl)-2-oxobutanoic acid, 4-(2-furtyl)-2-hydroxybutanoic acid, and aliphatic hydrogenolysis products of the initial compound were obtained. The sodium salt of 2-hydroxy-4-(2-tetrahydrofuryl) butanoic acid and the condensation product 4-(2-furylethyl)-3-(2-furylmethyl)-2-oxo-3,4-didehydroglutaric acid were detected in the hydrogenolysate. A method has been developed for obtaining the sodium salts of 4-(2-furyl)-2-oxobutanoic and 4-(2-furyl)-2-hydroxybutanoic acids.
