3,6-Anhydro-5-<I>O</I>-methyl-D-galactose has been synthesized for the first time through a series of reactions composed of blocking the hydroxyl groups at C<SUB>2</SUB> and C<SUB>4</SUB> of methyl 3,6-anhydro-α-D-galactopyranoside with the phenylcarbamoyl groups, converting the resulting derivative of the methyl glycoside into the corresponding dimethyl acetal, methylating the newly formed hydroxyl group at C<SUB>5</SUB>, removing the blocking substituents, and finally hydrolysing the dimethyl acetal. The partially methylated anhydro-sugar obtained was uncrystallizable, and was characterized by its crystalline dimethyl acetal and crystalline aldonamide.
