A mixture of N-(L-α-aspartyl)- and N-(L-β-aspartyl)-β-D-glucopyranosylamine was obtained by the condensation of N-(benzyloxycarbonyl)-L-aspartic anhydride with β-D-glucopyranosylamine.Attempts to separate the mixture by using cation-exchange chromatography, a copper(II) complex, and fractional recrystallization were carried out.These separations gave good yields of the desired β-amine.

The chromatographic resolution of enantiomeric amino acids is accomplished on reverse phase columns using aqueous mobile phases containing the chiral reagent L-aspartylcyclohexylamide-Cu(II).This reagent has the additional advantage that t
