Reaktionsschritte

0.16 g (1.00 mmol) of the compound (3) was dissolved in 50 ml of water, followed by adding 4.00 g of amberlight IR-120B (proton type cation exchange resin) to the resultant solution. The system thus prepared was kept stirred for 8.5 hours at 100° C. Then, the amberlight IR-120B was removed from the reaction system by means of filtration, followed by washing the cation exchange resin with water. Further, the solvent was removed from the filtrate and the washing water by means of distillation under reduced pressure. Formation of the desired compound of the present invention, i.e., D-altrose (compound 4), was confirmed by thin layer chromatography. It was also confirmed that the raw material compound (3) was mixed with the product compound (4). The mixing ratio of these compounds (3) and (4) was about 1:1.
