Fig. 8. Partial two-dimensional HMQC spectrum of species D-1, showing direct bond 1H-13C correlations within the sugar ring region.

Fig. 8

The assigned cross-peaks are labeled. Comparison with Fig. 6 reveals that the C-1′/H-1′, C-1″/H-1″, and C-2′/H-2′ cross-peaks in D-1 resonate at almost identical shifts as those in B. However, the C-2/H-2 cross-peak at 53.0/4.08 ppm in B is shifted to 57.0/4.42 ppm in D-1, and the C-1/H-1 cross-peak is not seen in D-1, consistent with the presence of a proximal aminogluconate unit in D-1.
