This was washed with an aqueous sodium carbonate solution and further washed with a saturated saline solution. The methylene chloride layer was dehydrated with Glauber's salt and concentrated, leaving 4.6 g of oily residue.

After dissolving in dioxane and adding 1 ml of water,
40-g of sodium borohydride was slowly added. After stirring overnight at room temperature, the mixture was made weakly acidic with diluted hydrochloric acid, extracted with chloroform, washed with water, dehydrated, acetylated with acetic anhydride in pyridine, and worked up in a conventional manner to obtain 0.42 g of an oil. This oily substance was analyzed by nuclear magnetic resonance spectroscopy.
The chemical shift value of the ring proton at sugar 02 position is 5.09p
It was a doublet of 1OHZ and 3.6Hz on the p own. Furthermore, other chemical shift values were completely consistent with the results of Example 2. Since no other impurity peaks were observed, it was determined that only a compound in which the acetoquine group at the 2-position of the sugar skeleton was in the equatorial (equatorial) configuration was produced.
