Toluene → 2,3,4,6-Tetra-O-acetyl-beta-D-glucopyranosyl chloride

Participants

Reaction Steps

To a solution of β-D-glucose pentaacetate (20 g) in CHCl3 (100 mL) was added AlCl3 (3.6 g). After stirring at room temperature, toluene (100 mL) was added, followed by silicic acid (2 g). The mixture was stirred for a few minutes and the precipitate was removed by filtration. The solution was partially concentrated under vacuum and extracted with ice cold water (25 mL). The organic phase was concentrated to a syrupy mixture and ether was added to precipitate acetochloro-β-D-glucose as a powder (12 g).
