  Tricyclic “oxadiazaphosphorine oxide” guanosines: A new strategy to the protection of guanine bases during RNA synthesis

  摘要：

  A novel strategy for simultaneously protecting the lactam and N2-amino functions of guanine nucleosides is reported. N2-benzoylated guanosines were readily converted into tricyclic "oxadiazaphosphorine oxide" guanosines upon reaction with N,N-diisopropylphosphoramidous dichloride followed by oxidation with t-butyl hydroperoxide. The tricyclic guanine derivative is reconverted readily to the natural guanine aglycone upon treatment with ethylenediamine/ethanol (1:4, 1 min, r.t.).
