Abstract
An α-amido-β-ketoamide (1) and two α-alkyl-β-ketoamides (2 and 3) were prepared and characterized, and their keto-enol tautomerism was studied by H/13C NMR spectroscopy. Both α-alkyl-β-ketoamides 2 and 3 are in the keto form in CDCl3, and their enol forms cannot be detected by 1H/13C NMR spectroscopy, whereas the α-amido-β-ketoamide 1 shows both keto and enol forms in CDCl3 with an experimental KE of 0,70 at 298 K.
