<p>PROBLEM TO BE SOLVED: To provide techniques for efficient chemical synthesis of sugar chains.SOLUTION: There are provided sugar derivatives represented by the formula (Ia) in the figure and methods of synthesizing sugar chains using the same. [In the formula, Rrepresents a pivaloyl group; Rtogether represent a benzylidene group; Reach represent a hydrogen atom or a tert-butyldiphenylsilyl or acetyl group protected hydroxy group, where one of Rrepresents a hydrogen atom and the other represents a tert-butyldiphenylsilyl or acetyl group protected hydroxy group; Ris a protected or unprotected hydroxy group; Rare identical or different and each represent a protected or unprotected hydroxy group or a protected or unprotected amino group; Rare identical or different and each represent a hydrogen atom or a hydroxy group protecting group; and n represents an integer between 1 and 3.]</p> |
