such as the glycogen debranching enzyme. The deoxy derivatives were prepared starting from maltose and maltotriose, respectively. Deoxygenation of the terminal 4-hydroxyl group was accomplished by radical reduction of the iodo sugar formed after iodide displacement of the corresponding protected triflate. The anomeric fluoride was introduced by treatment of the protected hemiacetal with diethylaminosulfur
