The 15N NMR spectra of a series of derivatives of 2‐amino‐2‐deoxy‐β‐D‐glucopyranose and dipeptides or secondary amines were recorded. In the dipeptide derivatives the chemical shift of nitrogen atom N‐1 (linked to sugar) is essentially unchanged and the shifts of nitrogen atoms N‐3 and N‐6 are determined by the nature of the R1 and R2 substituents at C‐α carbon of the amino acid unit. The highest shielding
