摘要
Mild and stereoselective arylthio glycoside syntheses were accomplished by inversion of configuration of glycosyl halides under phase transfer catalyzed conditions. Under such conditions, aryl alpha-thiosialosides having electron donating and withdrawing substituents were evaluated as active and latent thioglycosyl donors. A sialyl-alpha-(2-->6)-galactoside was prepared in good yield using the above strategy.
