We have discovered that N-alkyl aminomalonates undergo a fast and selective intramolecular C→N acyl rearrangement reaction in the presence of a strong base, leading to N-protected glycinates in excellent yield. Moreover, the fact that the reaction proceeds through a nucleophilic enolate intermediate has been used for implementing a tandem rearrangement/alkylation sequence that has been applied to the preparation of synthetically relevant nonproteinogenic tertiary and quaternary N-alkyl α-amino acids in a very simple and reliable way.
