Abstract: Nitromethane synthesis with the corresponding aldoheptoses followed by oxidative decomposition of the formed sodium salts of 1-deoxy-l-nitrooctitols led to preparation of D-erytro-L-galactooctose, D-erytro-L-talooctose, D-threo-L-galactooctose, and D-threo-L-talooctose. High efficiency of the separation on a Dowex 50 W ion exchanger (in the Ba2+ form) of the epimeric pairs of aldoses belonging to the homomorphous series of arabinose and ribose was demonstrated in nine cases.
