The present invention provides a process for the synthesis of 2-deoxy-D-glucose comprising haloalkoxylation of R-D-Glucal wherein R is selected from H and 3, 4, 6-tri-O-benzyl, to obtain alkyl 2-deoxy-2-halo-R-α/β-D-gluco/mannopyranoside, converting alkyl 2-deoxy-2-halo-R-α/$(b)-D-gluco/mannopyranoside by reduction to alkyl 2-deoxy-α/$(b)-D-glucopyranoside, hydrolysing alkyl 2-deoxy-α/$(b)-D-glucopyranoside to 2-deoxy-D-glucose.

2-deoxy-α-d-glucopyranoside derivatives is also reported. Their configuration was confirmed by single crystal X-ray analysis of the key intermediate 2,6-dichloro-9-(2-iodo-2-deoxy-α-d-glucopyranosyl)purine. Convenient and stereoselective methods for the preparation of 2-deoxy-d-glucose and purine 2-deoxy-α-d-glucopyranonucleosides were developed.
