This paper reports the polycondensation of benzyl 2-amino-2-deoxy-α-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 CO2 was carried out in DMF solvent in the presence of the condensing agent under CO2 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.
