Butyllithium was directly added to the solution of polysaccharides in dimethyl sulfoxide. The methylsulfinyl carbanion, as a sugar alkoxide forming reagent, was generated from the solution. All the operations were performed as one-pot reactions. Five polysaccharides from different traditional Chinese medicines and three dextrans were methylated and satisfactory results have been achieved.
