Abstract: Molybdic acid epimerizes aldoses under formation of an equilibrium mixture consisting of C-2 epimeric aldoses, whereas peroxomolybdic acid inhibits the epimerization reaction. Peroxomolybdic acid was also responsible for both the stereoselective hydroxylation of glycals to aldoses with a cis arrangement of hydroxyl groups at carbon atoms C-2 and C-3 and oxidative decomposition of alkali metal salts of 1-deoxy-1-nitroalditols to the corresponding aldoses; it simultaneously prevented the subsequent epimerization of aldoses being formed.
