以氯甲酸乙酯、氯甲酸丁酯、氟甲酸丁酯和1h -咪唑-1-羧酸酯为原料合成了右旋糖酐碳酸烷基酯。研究了反应条件对反应效率和取代图的影响。所得产物的结构通过核磁共振和红外光谱得到了清晰的描述。
Dextran alkyl carbonates were synthesized applying ethyl chloroformate, butyl chloroformate, butyl fluoroformate and 1H-imidazole-1-carboxylates. The influence of the reaction conditions on the reaction efficiency and the substitution pattern was studied in detail. The structure of the products obtained was clearly described by means of NMR- and IR-spectroscopy.
