Boron Trifluoride-Catalyzed Rearrangement of 2-Aryloxytetrahydropyrans: A New Entry to C-Arylglycosidation
Kometani, Tadashi,Kondo, Hiroyuki,Fujimori, Yukio
, p. 1005 - 1007 (1988)
Treatment of 2-aryloxytetrahydropyrans with boron trifluoride afforded 2-aryltetrahydropyrans via rearrangement in good yield.Aryl O-glycopyranosides were converted into the corresponding C-glycopyranosides by the same procedure.
