Process for producing amino acid derivatives, in which (a) an organic amine, the amino functionality of which is protected, or an α-amino acid, the amino functionality of which is protected, is subjected to an electrochemical reaction so as to form an amine which is activated in the α-position; (b) the activated amine is subjected to a reaction with a carbanionic reagent containing at least 3 carbon atoms and comprising an unsaturated group so as to form an unsaturated amine comprising an unsaturated group, the atom of the unsaturated group closest to the nitrogen being separated from the nitrogen by at least 2 carbon atoms; (c) the unsaturated amine is subjected to oxidation of the unsaturated group so as to form an amino acid derivative.
