2,3,4,6-TETRA-O-BENZYL-ALPHA-D-GLUCOPYRANOSE Chemical Properties,Usage,Production

Description

2,3,4,6-Tetra-O-benzyl-D-glucopyranose is a selectively protected intermediate, where the anomeric 1-O-hydroxyl group is free. This hemiacetal has been used successfully as an intermediate for glucosylation couplings, where it was converted into 2,3,4,6-tetra-O-benzyl-D-glucopyranose trichloroacetimidate using trichloroacetonitrile in the presence of a base such as potassium carbonate and DBU.
Importantly, this imidate donor with no neighbouring participating groups is commonly used for the selective formation of glucosides. 2,3,4,6-tetra-O-benzyl-D-glucopyranose can also be oxidized to the lactone, or reduced to give the open chain form.
Additionally, 2,3,4,6-tetra-O-benzyl-D-glucopyranose can be used for the preparation of glucono-1,5-lactone hydrazine, which was used, in-turn, to form a glucosylidene-spirocyclopropane.

Uses

It is the intermediate of Voglibose/Dapagliflozin. An important D-glucopyranose derivative for glucosylations and other reactions 1,2; Preparation of the α-glucopyranosyl chloride, synthesis of 1-C-α-D-glucopyranose derivatives.

Synthesis

Octa-O-Dissolves benzyl sucrose or octa-O-allyl sucrose in an organic solvent with the addition of hydrochloric acid without prior chromatographic purification, allows it to react for 20-60 minutes at temperatures of 50-60 °C. and then cleans the end product formed by crystallization. (ethanol, isopropanol, acetone, benzene, toluene or mixtures thereof can be used as solvents).
