Facile synthesis of per-O-tort-butyldimethylsilyl-β-D-galactofuranose and efficient glyeosylation via the galactofuranosyl iodide

The synthesis of crystalline per-0-TBS-β-D-galactofuranose (Aβ) as a new precursor of D-Galf units is described. Anomeric iodination by reaction with TMSI followed by in situ coupling with simple alcohols and a wide variety of glycosyl acceptors, in the absence of a promoter, was employed as a new e...
