A straightforward synthesis of 2,3-diaminobutanoic acids is reported. The synthesis is based on the nucleophilic addition of methylmagnesium bromide to differentially protected nitrones derived from l-serine. The change of the protecting groups in the starting nitrone is crucial for the stereocontrol of the reaction.
