2,3,4,6-Tetra-O-benzyl-D-glucopyranose Chemical Properties,Uses,Production
Description
2,3,4,6-Tetra-O-benzyl-D-glucopyranose is an important D-glucopyranose derivative, which is often used as a pharmaceutical intermediate in the synthesis of derivatives for the treatment of Alzheimer's disease, diabetes, and cancer.
Chemical Properties
White Crystaline Solid
Uses
2,3,4,6-Tetra-O-benzyl-D-glucopyranose (cas# 4132-28-9) is a compound useful in organic synthesis. For example, it enables the preparation of α-glucopyranosyl chloride as well as 1-C-α-D-glucopyranosyl derivatives; it can also be used in the preparation of important D-glucopyranosyl derivatives for glucosylation and other reactions.
Synthesis
Add 19.4g of 2,3,4,6-tetra-O-benzyl-β-D-glucosinolate to 500mL of acetone, and add 18.7g of N-bromosuccinyl in batches with stirring Imine (NBS), after the addition, react at 25°C for 0.5h. Most of the acetone was evaporated under reduced pressure, and a white solid was precipitated, which was diluted by adding 200 mL of 1mol/L hydrochloric acid and allowed to stand at -18°C for 3h. After suction filtration, the filter cake was washed with cold absolute ethanol, and recrystallized with absolute ethanol-cyclohexane to obtain 15.6 g of white flocculent solid 2,3,4,6-Tetra-O-benzyl-D-glucopyranose with a yield of 96.6%.
