PROBLEM TO BE SOLVED: To provide a new efficient method for producing a fucosylα(1→3)chitobiose derivative, dealable with a large amount of preparation, and a new glucosamine derivative applicable to the method. SOLUTION: This method for producing the fucosylα(1→3) chitobiose derivative includes a process of ring-opening of the 1, 6-anhydrous ring of a compound expressed by formula (IV) [wherein, R<SB>1</SB>to R<SB>3</SB>and R<SB>6</SB>to R<SB>8</SB>are each same or different substituent such as H, acetyl, benzyl, p-methoxybenzyl or o-nitrobenzyl; and R<SB>9</SB>is H or a lower alkyl]. Further, a polymeric compound carrying the fucosylα(1→3) chitobiose derivative produced by the method is provided. Also, an N-acetyl glucosamine derivative utilizable for the practice of the disclosure is provided. COPYRIGHT: (C)2011,JPO&INPIT |
