The herein described studies on the enolization and subsequent alkylation of the acyclic glycine title ester evidence the involvement of the kinetics of the alkylation step on the stereochemical outcome of the overall process, apart from that of the deprotonation sequence itself.Careful choice of reaction conditions allow for the selective obtention of α-amino acids either of the L- or the D-series without the need of changing the chiral inducer: deprotonation with LDA or t-BuLi followed by reaction with alkyl triflates gives rise to the 2R- α-amino acids, whereas the 2S isomers can be obtained by deprotonation with KO-t-Bu followed by reaction with alkyl halides.
