  Synthesis of 2′‐Substituted MMI Linked Nucleosidic Dimers: An Optimization Study in Search of High Affinity Oligonucleotides for Use in Antisense Constructs

  摘要：

  The synthesis of a series of methylene(methylimino) (MMI) linked oligodeoxyribonucleotide dimers modified at the 2'-position with fluoro and/or methoxy groups and their incorporation into different sequences has been accomplished. From these dimers, his 2'-OMe MMI dimer was selected for further studies based on its synthetic accessibility and the increased thermodynamic stability conferred upon oligonucleotides incorporating this modification.

  An Efficient Multigram Synthesis of Monomers for the Preparation of Novel Oligonucleotides Containing Isosteric Non-Phosphorous Backbones

  摘要：

  The facile preparation of two novel classes of nucleoside analogs for the inclusion as dimeric non-phosphorous containing subunits in chimeric backbones has been accomplished. The concise preparation of 3'-formylnucleosides and 5'-O-(N-methylhydroxylamino)-nucleosides is reported.
