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.

Application

After activation with trifluoroacetic anhydride, 2,3,4,6-Tetra-O-benzyl-D-glucopyranose reacts with various silyl enol ethers or allyl silanes in the presence of Lewis acids to generate α-configured C-D-glucopyranosyl derivatives, and reacts with activated aromatic nucleophiles to generate the corresponding β-anomers^[2]. It can also be used to synthesize the antibiotic (+)-nojirimycin^[3].

Reactions

The coupling reaction of 2,3,4,6-tetra-O-benzyl-1-C-phenyl-α-D-glucopyranose with 2,3,4,6-tetra-O-benzyl-D-glucopyranose, in the presence of 5 mol% bismuth(III) triflate in dichloromethane at 0 °C, could synthesize 2,3,4,6-tetra-O-benzyl-1-C-phenyl-D-glucopyranosyl 2,3,4,6-tetra-O-benzyl-D-glucopyranoside[1].

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%.
