  Synthesis of nucleoside 3'-alkylphosphonates: intermediates for assembly of carbon-bridge dinucleotide analogs

  摘要：

  Several 3'-modified nucleosides have been prepared, through an initial Wittig or Horner-Wadsworth-Emmons condensation with an adenosine 3'-ketone, followed by catalytic hydrogenation of the resulting olefin. Subsequent reaction of the 3'alpha-methylene carboxylate with the lithium salt of diethyl ethylphosphonate gave a beta-keto phosphonate, while reaction of the methylene carboxylate with LDA, diethyl chlorophosphite, and O2 gives the corresponding alpha-phosphono ester. These new nucleoside phosphonates can be viewed as analogues of natural phosphates and also can serve as synthetic intermediates for preparation of carbon-bridged dinucleotide analogues. To give the first such example, the beta-keto phosphonate 13 was allowed to react with a nucleoside 5-aldehyde, affording the dinucleoside enone 23.
