Notes:
Diazo transfer from trifluoromethanesulfonyl azide (TfN3) to 2-amino-2-deoxy-glycoses constitutes a high-yielding, simple procedure for the preparation of partially protected or unprotected 2-azido-2-deoxy-aldoses. Thus, the D-allosamine derivative 2 gave 93% of 3, while diazo transfer to D-glucosamine, D-mannosamine, and D-galactosamine, followed by acetylation, yielded the azides 5, 7, and 9 in yields of 74-91, 65, and 70%, respectively.
