This paper reports the polycondensation of benzyl 2-amino-2-deoxy-a-D-glucopyranoside hydrochloride (1) with carbon dioxide using the triphenylphosphine/carbon tetrachloride/DBU system as a condensing agent to give poly(urethane) (2). The polycondensation of 1 with CO 2 was carried out in DMF solvent in the presence of the condensing agent under CO 2 atmosphere. From the NMR and IR analyses of the product, the polymerization proceeded regioselectively to form 2. The molecular weight was estimated as 2000-3000 by GPC measurement after acetylation of 2, corresponding to DP=5-8.
