C-4-Triflate Displacement by Azide in 2,3-Anhydro Sugars; a New Way to 4-Amino-4-deoxy Sugars

Displacement of the triflyl by the azido group in benzyl-2,3-anhydro-4-triflyl-α-D-pyranosides 4-6 gives with inversion the benzyl-2,3-anhydro-4-azido-4-deoxypyranosides 7-9.The triflyl group turns out to be a reactive leaving group which can be replaced
