promoted by alkoxyl radicals generated from 3-hydroxypropyl α- d -mannopyranoside derivative ( O -glycoside) and 2,6-anhydro- d - glycero - d - manno -decitol derivative ( C -glycoside) is studied. The O -glycoside model abstracts preferentially the hydrogen atom at C-5 (1,8-HAT) while the C -glycoside abstracts the hydrogen atom at C-1 (1,6-HAT) but no abstraction at C-5 could be detected. These results
