On D-lactose, C-6 and C-6′ which have the primary hydroxy groups were selectively triphenylmethylated and the remaining secondary hydroxy groups were acetylated. During detriphenylmethylation, acyl migration occurred to give acetylated lactose having free hydroxy groups on C-6 and C-46′. Polycondensation of the obtained 1,2,3,2′,3′,6′-hexa-O-acetyl-D-lactose and terephthaloyl chloride gave the aromatic polyester having lactose in the main chain.
