STEREOSELECTIVE SYNTHESIS OF α-D-GLUCOPYRANOSIDES VIA 6-SILYL-α-D-GLUCOPYRANOSYL BROMIDES
Bromotrimethylsilane cleaved 2,3,4-tri-O-benzyl-1,6-anhydro-β-D-glucopyranose (1) to give 2,3,4-tri-O-benzyl-6-O-trimethylsilyl-α-D-glucopyranosyl bromide (2).Reaction of 2 with ROH/diisopropylethylamine gave the corresponding α-glucopyranosides.
