reaction from deoxyguanosine and used for preparation of the building blocks of deoxyguanosine required for the polymer support synthesis. Two kinds of polymer supports, i.e., 1% cross-linked polystyrene and controlled pore glass were chosen. The latter was employed for the synthesis of dodecadeoxyribonucleotides by using an automated DNA synthesizer.
利用苯硫基作为磷酸保护基团的寡聚脱氧核糖核苷酸合成应用于固相法。脱氧鸟苷和脱氧腺苷的碱基残基分别用双(异丁酰氧基)亚乙基(Bibe)和邻苯二甲酰基保护,以避免碱基修饰和脱嘌呤。N2-异丁酰-N1,N2-双(异丁酰氧基)亚乙基脱氧鸟苷的关键合成中间体通过脱氧鸟苷的四步反应以高收率制备,用于制备聚合物载体合成所需的脱氧鸟苷结构单元。选择了两种聚合物载体,即1%的交联聚苯乙烯和可控孔玻璃。后者用于通过使用自动 DNA 合成仪合成十二氧核糖核苷酸。
