A new synthesis of ether-linked sugar utilizing the nucleophilic ring-opening reaction of carbohydrate α- or β-oxirane was developed. The reaction of 2,3-anhydro-α-D-mannopyranosides resulted in the expected high regioselectivity. In contrast, 2,3-anhydro-α-D-allopyranosides showed an unusual regioselectivity shift. The differentiating properties of carbohydrate α- or β-oxirane were investigated by comparing various conditions of the reaction.
