An improvedsynthesis of anhydroalditols through reductive cleavage of acetylated carbohydrates is reported. The procedure appears to have generality. Ring rearrangements, which complicate some other reported procedures for the preparation of anhydroalditols, were not observed. The acetate protecting groups used were stable under the reaction conditions employed.
