Two versatile, high yielding, and efficient chemo-enzymatic methods for the synthesis of β-protected Asp and γ-protected Glu derivatives using Alcalase are described. The first method is based on the α-selective enzymatic hydrolysis of symmetrical aspartyl and glutamyl diesters. The second method involving mixed diesters comprises a three-step protocol using (i) α-selective enzymatic methyl-esterification, (ii) chemical β-esterification, and finally (iii) α-selective enzymatic methyl ester hydrolysis. The yields of the purified β- and γ-esters range from 77% to 91%.

Asparatic acid side chain protection by allyl ester functions has been facilitated by the direct synthesis of Z-Asp(OAll)-OH which can be performed by selective hydrolysis of Z-Asp(OAll)-OAll by means of papain catalysis.Both an optimization study and a batch synthesis are reported.Other synthesis routes are discussed.

(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.
