preparation of the dinucleotide hybrid 5'-O-phosphoryl-2'-deoxycytidylyl-(3'--> 5')adenosine (pdCpA) 7. This simple and concise synthesis involves the successive coupling of 2-cyanoethyl N, N, N', N'-tetra- isopropylphosphorodiamidite with 4-N-benzoyl-5'-O-(4, 4'-dimethoxytrityl)-2'-deoxy-cytidine 1 and 6-N,6-N,2'-O,3'-O-tetrabenzoyladenosine 2 as the key step. Some dinucleotide derivatives bearing
为制备二核苷酸杂合体5'-O-磷酰基-2'-脱氧胞嘧啶-(3'-> 5')腺苷(pdCpA)7开发了一条改进的途径。这种简单而简明的合成方法涉及2的连续偶联-氰基乙基N,N,N',N'-四异丙基亚磷酰胺基与4-N-苯甲酰基-5'-O-(4,4'-二甲氧基三苯甲基)-2'-脱氧胞苷1和6-N,6- N,2'-O,3'-O-四苯甲酰腺苷2是关键步骤。还合成了一些带有不同保护基的二核苷酸衍生物,并详细研究了选择性脱保护条件。该方法在合成总DNA二核苷酸pdCpdA 17和总RNA二核苷酸21中的应用进一步证明了该方法的实用性和效率。
