Reaktionsschritte

0.16 g (1.00 mmol) of the compound (3) was dissolved in 5 ml of 1N sulfuric acid, and the resultant solution was kept stirred for 5 hours at 100° C. The reaction mixture was passed through an anion exchange resin (hydroxyl ion type amberlight IRA-410) for neutralizing purposes, followed by removing the solvent 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.
