Alcohols in small peptides, monosaccharides and steroids (12 examples) are conveniently transformed to their corresponding nitrate esters upon treatment with an acetonitrile solution of LiNO3 and trifluoroacetic anhydride. The in situ formed mixed anhydride (CF3COONO2) is proposed to be the reactive nitration reagent.

A new procedure for the C1–C2 fragmentation of cyclic carbohydrates, through the formation of anomeric alkoxy radicals from the corresponding nitrate esters, with nBu3SnH/azobisisobutyronitrile (AIBN), affords acyclic alditols in good yields.
