protected building units for oligodeoxyribonucleotide synthesis in the phosphoramidite approach were prepared in high yields by the 5′-dimethoxytritylation of N-[4,4′,4″-tris(benzoyloxy)trityl]deoxyribonucleosides followed by the 3′-phosphitylation with methoxymorpholinochlorophosphine. The solid phase synthesis of oligodeoxyribonucleotides on a controlled pore glass gel using the amidite units was examined
通过 N-[4,4',4"-三(苯甲酰氧基)三苯甲基]脱氧核糖核苷的 5'-二甲氧基三苯甲基化,然后用甲氧基吗啉代氯膦进行 3'-亚磷酸化,以高产率制备了用于亚磷酰胺方法中寡脱氧核糖核苷酸合成的完全保护的构建单元. 检查了使用亚酰胺单元在受控孔玻璃凝胶上的寡脱氧核糖核苷酸的固相合成。详细讨论了冷凝效率。4,4',4"-三(苯甲酰氧基)三苯甲基(TBTr)基团从受控孔玻璃凝胶上合成的受保护四聚体中快速去除,得到 dGpCpApT。
