By starting with 3′-keto-5′-O-protected thymidine, 3′-O-amino-5′-t-butyl-diphenylsilyl thymidine (9) was prepared and coupled with 3′-O-t-butyl-diphenylsilyl-5′-formyl thymidine to form a nucleoside dimer (11) containing oxime linkage. The back bone of this dimer, then, under went reduction followed by acetylation to give an (N-acetyl)imino linkage, and a novel dinucleotide (13) was obtained.
从 3'-keto-5'-O-protected thymidine 开始,制备 3'-O-amino-5'-t-butyl-diphenylsilyl thymidine (9) 并与 3'-Ot-butyl-diphenylsilyl-5 偶联'-甲酰基胸苷形成含有肟键的核苷二聚体 (11)。然后,该二聚体的主链被还原,随后乙酰化产生(N-乙酰)亚氨基键,并获得新的二核苷酸(13)。
