ABSTRACT:
A sugar derivative wherein a hydroxy-carboxylic acid is combined to a position 1 of a sugar via ether linkage, and other hydroxyl groups are protected with a protective groups. A method of producing the sugar derivative, comprises allowing glycolic ester to react with a compound so as to combine said glycolic ester at the position 1 of the sugar skeleton, and then saponifying, said compound has on the position 1 any of hydroxyl group, halogen atom and sulfur atom with a substitutent group, and has other hydroxyl groups being protected with a protective groups.
