  Synthesis of Oligo(Deoxyribonucleoside Phosphorodithioate)s by the Dithiaphospholane Approach

  摘要：

  A novel method of synthesis of oligo(deoxyribonucleoside phosphorodithioate)s (S-2-ODNs), based on the ring-opening condensation of nucleoside 3'-0-(2-thiono-1,3,2-dithiaphospholane)s with 5'-O-deprotected nucleosi(ti)des in the presence of a strong organic base such as DBU, is presented. The process has been adapted to the requirements of automated solid-phase oligonucleotide synthesis with a relatively short condensation step (5 min) and reasonable step-yield(>95%). N-Methylpyrrolidin-2-ylidenyl (Pya) was found to be the group of choice for the protection of reactive aminofunctions of nucleobases in nucleotide substrates. Sarcosine-containing linker (LCA CPG SAR) was employed due to its known resistance to cleavage by DBU. Several medium-size S-2-ODNs were prepared by this approach. Their identity and purity was confirmed by means of P-31 NMR, gel electrophoresis, and mass spectrometry. It has been demonstrated that, contrary to a recent report, S-2-ODNs are not degraded by DNaseI.

  Synthesis of P-Fluorodithioacids of Phosphorus and Their Synthetic Application

  摘要：

  Oligonucleotides containing 3'-S-P(S) and 5-S-P(S) fragments in the deoxy-series are available only by tedious multistep procedures. We have developed a novel and efficient methodology based on ring opening of anhydronucleosides by phosphorus dithioacids. This approach allows efficient synthesis of modified dinucleotides of the ribo-series.

• The synthesis of di- and oligo-nucleotides containing a phosphorodithioate internucleotide linkage with one of the sulfur atoms in a 5′-bridging position

  phosphorodithioate linkage is described, wherein one of the sulfur atoms occupies a 5′-bridging position. Representative dinucleotides possessing such a bond were synthesized by S-alkylation of nucleoside-3′-O-phosphorodithioates with 5′-halogeno-5′-deoxy-nucleosides. A fully protected dithymidylate containing internucleotide 5′-S-phosphorodithioate linkage was converted into a 3′-O-phosphoramidite

  描述了一种新型的核苷酸间二硫代磷酸酯键，其中一个硫原子占据5'-桥接位置。具有这种键的代表性二核苷酸是通过将核苷-3'- O-二硫代磷酸酯与5'-卤素-5'-脱氧核苷进行S-烷基化而合成的。将含有核苷酸间5'- S-二硫代磷酸酯键的完全保护的二胸苷酸转化为3'- O-亚磷酰胺衍生物，并用于将修饰的二核苷酸引入寡核苷酸序列的预定位置。5'- S发现二核苷酸类似物中的β-二硫代磷酸酯键抗蛇毒PDE和核酸酶P1的核酸降解。然而，在小牛脾PDE处理下，观察到5'- S-二硫代磷酸二硫代二胸苷类似物的非对映异构体的P-立体选择性降解。在碘的存在下碘溶液容易降解新的5'- S-磷酸二硫酯键。水。还发现含有单个5'- S-磷酸二硫酯键的寡胸苷酸酯与其互补序列形成弱得多的双链体。

  Four dinucleoside phosphorodithioates: TPS2T (1a), d(CPS2C) (1b), dAPS2A} and d(GPS2G) (1d) were synthesized by reacting solid support-bound nucleosides with nucleoside 5′-O-DMT-3′-O-(2-thio-1,3,2-dithiaphospholanes) (2a-d) in the presence of DBU. Pyrimidine pentamers, free from phosphorothioate contamination, were obtained by this method.
