  An Olefin Cross-Metathesis Approach to Vinylphosphonate-Linked Nucleic Acids

  摘要：

  [GRAPHICS]The synthesis of vinylphosphonate-linked nucleotide dimers has been achieved using an olefin cross-metathesis (CM) reaction as a key step. The 1,3-dimesityl-4,5-dihydroimidazol-2-ylidine-containing catalyst 5 (Grubbs' second-generation catalyst) was found to be the superior catalyst for this transformation. Both metathesis partners were readily available using known methodology, and the vinylphosphonate-linked dimer was produced with high levels of (E)-selectivity (> 20:1) in 58% yield (70% based on recovered starting material).
