over, the results including the simple and environmen-
tally benign protocol14 and the good yield and stereose-
lectivity should find wide application in the synthesis of
biomolecules and functional materials containing car-
bohydrate(s). Further studies along this line are cur-
rently in progress.

14. Typical procedure: To a mixture of the glucopyranosyl
diethyl phosphite 1 (0.1 mmol) and alcohol (0.2 mmol)
was added C6mim[NTf2] (1.0 M for 1) containing HNTf2
(1 mol% to C6mim[NTf2]). After stirring for 1 h at 25°C,
the mixture was extracted with a mixture of 5:1 hexane–
ethyl acetate and the combined extracts were concen-
trated in vacuo. Purification of the residue by flash
column chromatography gave the glucopyranosides. All
glucopyranosides were fully characterized by spectro-
scopic means and found identical with the authentic
samples, and the a/b ratios were determined by HPLC
analysis.
