in alpha-D-Hex p-(1-->4)-D-Hex p disaccharide models is described. These radicals are generated from a 6-O-yl radical located in the other monosaccharic unit through a 1,8-hydrogenatomtransfer. The reaction, which is strongly influenced by steric and stereoelectronic effects, permits in some cases the transformation of alpha-D-Hex p-(1-->4)-D-Hex p into beta-L-Hex p-(1-->4)-D-Hex p disaccharides
