Treatment of α-t-butyl β-methyl N-Z-(S)-aspartate (2) with lithium amide bases generates the corresponding β-ester enolate, which can be alkylated with suitable electrophiles.The application of this strategy for synthesis of optically active amino acids h

(S)-1-t-Butyl 4-methyl N-benzyloxycarbonylaspartate (5a), and (S)-1-t-butyl 4-allyl N-benzyloxycarbonylaspartate (5b) have been synthesized from (S)-aspartic acid (2), and can be readily alkylated and hydroxyalkylated at the β-carbon for asymmetric amino acid synthesis.
