STEREOSELECTIVE C-C BOND FORMATION IN CARBOHYDRATES BY RADICAL CYCLIZATION REACTIONS -- III. STRATEGY FOR THE PREPARATION OF C(1)-GLYCOSIDES.

Article abstract of DOI:10.1016/S0040-4039(01)93879-1

A new strategy for the stereoselective synthesis of α- and β-C(1)-glycosides based on an intramolecular radical cyclization reaction is described.Intramolecular hydrogen atom transfer was observed depending on the concentration of the reagents, the conformation and the substitution of the cyclized radical.
