Partial ¹H and ¹³C NMR spectra of TPM-L3 focusing on the anomeric and aromatic regions (see Fig. S2 for the full range of the spectra), (top) ¹H NMR spectrum of TPM-L3 gave a doublet at 4.33 ppm, along with a coupling constant (³J_aa) of 8.0 Hz, a typical peak characteristic for β-anomeric proton (H_a). This agent also contains α-anomeric protons (H_e), giving a doublet at 5.13 ppm with a reduced coupling constant (³J_ae = 4.0 Hz). H_a and H_e indicate anomeric protons in the axial and equatorial positions, respectively. Aromatic protons of the terphenyl group were well resolved in the region from 6.9 to 7.8 ppm in this spectrum. (bottom) The anomeric protons (H_a and H_e) of TPM-L3 gave peaks at 103.0 and 105.1 ppm in the ¹³C NMR spectrum while peaks corresponding to the aromatic protons dispersedly appeared in a range of 126 to 161 ppm. The chemical structure of TPM-L3 including the anomeric and aromatic regions is shown to illustrate the anomeric protons of interest. Dotted and solid boxes on the spectra represent the aromatic and anomeric regions, respectively.
