A series of pyranosidic and furanosidic monosaccharide derivatives were monoacetylated in the 6-position with high regioselectivity and good to excellent yields by the pancreatin-catalyzed transesterification with vinyl acetate in the solvent system tetrahydrofuran/triethylamine.

2,3:5,6-di-O-isopropylidene-d-manno-furanoside (15) with simultaneous conversion into the corresponding acetylatedglycosylfluorides (8, 12, 16). The second acetal function in 11 and 15 is not cleaved by the weakened HF medium. 2-O-Benzyl-protected sugars such as methyl 3,5,6-tri-O-methyl-2-O-benzyl-d-glucofuranoside (13) react intramolecularly in the presence of HF/nitromethane/acetic anhydride to
