Abstract

Acetolysis of 1, 6-anhydro sugars can be achieved by treatment with acetic anhydride and triethylsilyl trifluoromethanesulphonate at 0° C for 5–15 minutes, under which conditions a wide variety of protecting groups are unaffected, and even the trisulphonate is cleaved, albeit in six hours.
