2-Deoxy-2-iodo- and 2-deoxy-2-bromo-α-glucopyranosyl trichloroacetimidates: Highly reactive and stereoselective donors for the synthesis of 2-deoxy-β-glycosides

Roush, William R.,Gung, Benjamin W.,Bennett, Chad E.

, p. 891 - 893 (1999)

(equation presented) 2-Deoxy-2-iodo-and 2-deoxy-2-bromoglucopyranosyl trichloroacetimidates 8-10 and 22 are extremely useful precursors of 2-deoxy-β-glycosides. These reactive glycosyl donors undergo highly stereoselective glycosidation reactions at -78°C
