Enamine/imine tautomerism in α,β-unsaturated-α-amino acids

Article abstract of DOI:10.1016/S0040-4020(98)00908-9

Investigation of the α,β-unsaturated-α-amino acids-dehydrovaline, dehydrophenylalanine, and dehydropipecolinic acid-revealed that these compounds undergo rapid hydrolysis in neutral aqueous medium, via the imine tautomers, even when the corresponding este
