PROBLEM TO BE SOLVED: To provide a method capable of synthesizing a sugar chain containing a desired sugar at a desired position with a relatively high yield by a relatively simple process as compared with a conventional method. SOLUTION: Formula (I): (G 1 ) x (G 2 ) y (G 3 ) z -L -X wherein G 1 , G 2 and G 3 are each independently a monosaccharide residue having a cyclic structure or a derivative thereof; L is -O- (CH 2 ) n — and the like; X is —N 3 and the like; y and z are each independently an integer from 0 to 10; n is an integer from 8 to 20. Where x, y and z Are not 0 at the same time); a method for producing the same; a primer for sugar chain biosynthesis containing the compound; and a method for producing a virus or cytotoxin neutralizing substance of the primer or the like.
