[GRAPHICS]Participating acyl groups located at C-2 in glucosyl and related donors generally promote formation of 1,2-trans-glycosides. Reactions of some glucuronic acid donors with TMSN3/SnCl4 or ROH/SnCl4 gave only the 1,2-cis-glycoside. The stereoselectivity is consistent with participation of the C-6 group. The methodology was used for the synthesis of a Kdn2en mimetic with the alpha-configuration.

Monosaccharide (pyranoside) conjugates of the formula have been found to be useful as enhancers and/or inhibitors of heparin binding to FGF. The compounds have the potential to be useful in regenerative medicine or for treatment of pathological disease associated with FGF activity or as glycoprocessing inhibitors. In particular the compounds are potential modulators of fibroblast growth factors (FGFs) and fibronectin, as mitogenic agents and as inhibitors of endothelial cell survival.
