以2-脱氧-d-核糖和d-木糖衍生的二元醇为原料，经二硫化碳环硫代碳酸化反应，合成了硫代碳酸酯（-O-CS-O-）和黄原酸酯（-S-CS-O-）环状单体，然后采用有机催化剂开环聚合。得到了规则的聚合物键，糖主链影响单体开放的区域选择性。热分析表明，较低的玻璃化转变温度相比，碳酸酯类似物和低的热降解开始。
Thionocarbonate (-O-CS-O-) and xanthate (-S-CS-O-) cyclic monomers were synthesised by cyclothiocarbonation of 2-deoxy-d-ribose- and d-xylose-derived diols with carbon disulfide, then polymerised using organocatalytic ring-opening methods. Regular polymer linkages were obtained, with the sugar backbone influencing the regioselectivity of monomer opening. Thermal analysis revealed lower glass transition temperatures compared to carbonate analogues and a low onset of thermal degradation.
