| Abstract: | This paper reports the synthesis of 3-oxo-D-fructose diacetone derivative by oxidizing the secondary hydroxy of diacetone D-fructose with two novel oxidant systems: (a)CrO_3-Et_2O-CH_2Cl_2/celite, (b) PDC-(CF_3CO)_2O. Two branched-chain sugars 4,5 were obtained from 3-oxo-D-fructose. Their structuers were confirmed depending upon their elemental analysis and IR ~1H,~(13)C-NMR spec trum datum. |

| Keywords: | oxidation branched-chain sugar diacetone D-fructos-3-ulose |
