The 4-dimethylaminopyridine (DMAP) catalyzed ring-opening polymerization of lactide using various carbohydrate initiators has been assessed for the functionalization of polylactide. Selectively protected glucose derivatives bearing a free primary alcohol (Glc-1r) and a free secondary alcohol (Glc-2r), glucose and cyclodextrin diol derivatives (Glc-diol and CD-diol), methyl-α-d-glucopyranoside (Glc-Me) and native β-cyclodextrin (CD) were used as initiators. According to the solubility of the carbohydrate derivative, the polymerizations were conducted in chlorinated solvents and in the bulk. Relatively narrow distributions are obtained in high yields in the absence of side reactions, affording a 100% functionalization efficiency. The catalytic synthesis of new carbohydrate link-functionalized polylactides and carbohydrate core star polylactides is reported.
