摘要:

Glycosylations and deacetylations of 2-O-acetyl ofO-peracetylated β-D-glucopyranose were realized in one step by reactions with 4.0 equivalents of alcohols and 1.5 equivalents of trifluoroborane etherate. Thus, various β-D-glucopyranosides with a free hydroxyl group on C-2 were conveniently prepared and applied for synthesis of Glcl → 2 linked disaccharides.
