The synthesis of 2'-O-methylcytidylyl (3'-5')cytidine by the triester method using as protecting groups, 2,2,2-trichloroethyl for phosphate hydroxyl group, p-chlorophenyoxyacetyl for 5-hydroxyl group, methoxymethylidene for 2',3'-cis-diol system, and benzoyl for the exo-amino group of cytidine is presented. The obtained product was characterised by UV, electrophoresis, chromatography and an enzymatic digestion.
介绍了使用2,2,2-三氯乙基作为磷酸羟基的保护基团、对氯苯氧基乙酰基作为5-羟基的保护基团、甲氧基亚甲基作为2',3'-顺式二醇系统的保护基团以及苯甲酰基作为胞苷的外氨基保护基团,通过三酯法合成2'-O-甲基胞苷酰基(3'-5')胞苷。所得产物通过紫外光谱、电泳、色谱和酶消化进行表征。
