    • The product mixtures containing the fluorous compounds 13, 16 and 24 were partitioned between FC-72 and MeOH. Those containing the fluorous compound 14 and 22 were partitioned FC-72, toluene and water. The product containing the fluorous compound 21 was partitioned between FC-72 and acetonitrile. None of the fluorous compounds were detected by TLC of the organic layer after three times extraction with FC-72, which shows that these compounds were quantitatively extracted with FC-72.

    • The anomer ratio of compound 19 (the newly formed anomeric position) was determined to be α/β=60:40 by NMR spectroscopic analysis. Moreover, the correlation between anomeric protons of galactose residue and 6-position carbons of glucose residue of the compound 19 was observed by HMQC and HMBC of NMR spectroscopic analysis.
