  Facile methods to recycle nucleosides during solid phase synthesis of oligonucleotides

  摘要：

  Solid phase syntheses of oligonucleotides, using nucleoside phosphoramidites or methylphosphonamidites require a large excess of nucleoside monomers over the hydroxy functions of the growing oligonucleotide chain bound onto the solid phase. The outlined method allows to recover the excess nucleosides. All the protective groups on the sugar and the nucleobase of the monomers are maintained throughout the recycling process.

  H-膦酸酯二聚体的溶液相合成支链DNA杂种

  摘要：

  描述了一种溶液相合成具有四面体或伪八面体几何形状的分支寡核苷酸的方法，该方法包括将被保护的二核苷磷酸酯的3'- H-膦酸酯与有机核心分子偶联。二聚体结构单元是通过不需要色谱纯化的合成方法生产的，并且在不到三天的实验室工作中即可产生高达44％的H-膦酸酯二聚体。总共准备了七个不同的分支杂种，包括序列（CG）4 TBA的新杂种，其中TBA代表四（对-羟基联苯）金刚烷，它通过添加MgCl 2从微摩尔水溶液组装成一种材料。

  [GRAPHICS]A new solution-phase phosphoramidite approach is reported for oligonucleotide synthesis employing recyclable solid-supported reagents. It uses polyvinyl pyridinium tosylate as the activator of a nucleoside-3'-O-phosphoramidite in the coupling step with a 5'-OH nucleoside or dinucleotide. The resulting phosphite triester was either sulfurized or oxidized using polystyrene-bound trimethylammonium tetrathionate or periodiate. This method avoids complicated purification steps, as excess reagents are easily removed by filtration.
