Studies on<i>N</i>-Glycopeptides. II. Separation of α- and β-Amide of<i>N</i>-(L-Aspartyl)-β-D-glucopyranosylamine Obtained<i>via</i><i>N</i>-(Benzyloxycarbonyl)-L-aspartic Anhydride
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.
