Objective:To synthesize β-D-glucosyl esters in high yield and good stereoselectivity.Methods:1-O-trifuoroacetyl-2,3,4,6-tetra-O-acetyl-D- glycopyran reacts with carboxylic acid under low temperature, using BF 3·Et 2O as catalyst and CH 2Cl 2 as solven. Results:BF 3·Et 2O is a good catalyst.Low temperature is beneficial to yield of β-D-glucosyl esters.Conclusion:The method may apply to synthesize β-D-glucosyl esters.
