  摘要：

  描述了一种改进的磷酰胺法，用于制备用非环状、无手性的单体1修饰的寡核苷酸。对在固相或溶液中制备的二聚体的研究表明，含有烯丙基单元1的磷三酯二聚体对碱不稳定，而磷二酯二聚体则稳定。通过用磷酰胺基团3替换氰乙基磷酰胺基团2，可以获得磷二酯二聚体，后者在氧化后可直接生成。发现磷二酯二聚体对封闭和氧化稳定，但对酸有一定的敏感性。通过减少去三苷化过程中与酸的接触时间，可以制备含有4或8个修饰的A、G或T单位的寡核苷酸。这些修饰过的寡核苷酸能够与互补的DNA和RNA结合，但亲和力有所降低（每次修饰导致的ΔTm为−1到−5 °C）。

  Acyclic, achiral nucleoside derivatives 1b-e of adenine, cytosine, 5-methylcytosine, and guanine, containing a 3-hydroxy-2-(hydroxymethyl)prop-1-enyl group on N-1 or N-9, have been prepared analogously to the previously described thymine derivative 1a. In contrast to the adenine and guanine derivatives, the cytosine derivative 9 was unstable, and was obtained in a low yield due to side reactions. These

  nucleoside analogues 1a-f to undergo intramolecular cyclization reactions was investigated. All compounds, when treated with NaOD, were in equilibrium with the bicyclic compounds 2a-f, arising from Michael addition of a hydroxy group to the C(5)=C(6) bonds. Derivatives of 2,4-pyrimidinediones (1a,b) had the highest tendency to undergo intramolecular Michael addition when treated with triethylamine, whereas

  研究了一系列无环核苷类似物1a-f进行分子内环化反应的趋势。当用NaOD处理时，所有化合物均与双环化合物2a-f处于平衡状态，这是由于在C（5）= C（6）键上加成了羟基而形成的。当用三乙胺处理时，2,4-嘧啶二酮（1a，b）的衍生物具有最高的分子内迈克尔加成趋势，而用酸对4-氨基-2-吡啶酮（1c-f）的环化进行得最好。的环外双键对于环化的发生至关重要。常用的N-保护基如苯甲酰基和二丁基氨基亚甲基可增强环化作用。在酸性无水条件下1b和1e环化为2,4'-无水化合物1b和1e。

  An achiral, acyclic nucleoside analogue has been incorporated once or twice in oligodeoxyribonucleotides by the phosphoramidite method, and conditions found which allow deprotection of the oligonucleotides containing a sensitive modified allylic unit. The binding affinity of the modified oligonucleotides towards complementary DNA and RNA was reduced compared to unmodified DNA (DeltaT(m) -2 to -6.5degreesC). An oligonucleotide with two modifications at the 3'-end showed considerable resistance towards cleavage with a 3'-exonuclease. (C) 2003 Elsevier Science Ltd. All rights reserved.

  An improved phosphoramidite method is described to prepare oligonucleotides modified with the acyclic, achiral monomers 1. Examination of dimers, prepared on solid support or in solution, showed that phosphortriester dimers containing the allylic unit 1 were unstable towards bases, whereas phosphordiester dimers were stable. Phosphordiester dimers were obtained by replacing cyanoethyl phosphoramidites 2 with phosphoramidites 3, which gave phosphordiesters directly upon oxidation. The phosphordiester dimers were found to be stable towards capping and oxidation, but were somewhat labile towards acids. By reducing the contact time to acids during detritylation it was possible to prepare oligonucleotides containing 4 or 8 modified A, G or T units. The modified oligonucleotides hybridized to complementary DNA and RNA, although with reduced affinity (ΔTm per modification −1 to −5 °C).
