PROCEDURE

实验过程

The compound (16) (1.241 g), sodium pyruvate (1.200 g) and sodium azide (4.3 mg) were dissolved in distilled water (4.3 ml) and the pH of the resulting solution was adjusted to 10.59 by 2N sodium hydroxide. To this solution, 4.3 mg (112 U) of N-acetyl-neuraminic acid aldolase (NAL-300, manufactured by Toyobo Co., Ltd.) was added, followed by stirring mildly at 20° C. for 4 days. Thereafter, the reaction solution was desalted with an ion exchange resin (Dowex 50X8-200, H-type) and purified by an ion exchange chromatography (Dowex 1, HCOOH-type; aqueous 1.0M-HCOOH solution) to give 0.342 g of the candy-like titled compound (yield: 19.2%).
