Cleavage of 4,6- O -benzylidene acetal using sodium hydrogen sulfate monohydrate

The use of protecting groups is an important protocol in carbohydrate synthesis. Among protecting groups, benzylidene acetals are generally more stable than other acetals; therefore, strong conditions are often required for deprotection. We report the deprotection of 4,6-O-benzylidene derivatives using sodium hydrogen sulfate monohydrate under mild conditions. Georg Thieme Verlag Stuttgart New York.

Synthesis, crystalline structure, conformational analysis, and azidolysis of methyl 2,3-anhydro-α-D-manno- and -allo-pyranoside p-bromobenzyl ethers

Methyl 2,3-anhydro-4,6-di-O-p-bromobenzyl-α-D-allopyranoside (6) was synthesized from methyl 4,6-O-benzylidene-α-D-glucopyranoside (1) via the intermediate methyl 4,6-di-O-p-bromobenzyl-2,3-di-O-p-tolylsulfonyl-α-D-glucopyranoside.Treatment of 6 with sodi
