実験手順
10 g (25.6 mmoles) of α-D-glucose pentaacetate and 2 g (21.7 mmoles) of hydrazine acetate in N,N-dimethylformamide were together stirred at 50° C. for 45 minutes. The reaction solution was extracted with ethyl acetate, and washed with a saturated aqueous sodium chloride solution. After working up in a conventional manner, purification by silica gel column chromatography (eluent; ether: n-hexane =2:1 to 3:1) gave 5.45 g of 2,3,4,6-tetra-O-acetyl-α-D-glucose.
