  Synthesis of novel tetrazole C5-linked C0- and C2-ribonucleoside phosphoramidites using MePOM and POM groups for probing RNA catalysis

  摘要：

  Novel C5-linked C-0- and C-2-tetrazole ribonucleoside phosphoramidites were designed and synthesized via tetrazole C-nucleosides. Pivaloyloxymethyl (POM) and methyl-substituted POM (MePOM) groups were introduced as N-protecting groups in the tetrazole ring that can be readily removed under mild basic conditions. The phosphoramidites were successfully incorporated into the VS ribozyme substrate and hence providing a chemogenetic approach to determine which nucleobases of ribozymes function as the acid or base, in the studies of ribozyme general acid and base catalysis.

  Treatments of various nitriles with TMSN3 and Bu2Sn(OAc)2 at 30 oC in benzene for 60 h yielded the corresponding 5-substituted 1H-tetrazoles in good to excellent yields. This method is a mild and efficient alternative reagent system for Wittenberger tetrazole-synthesis that uses TMSN3 and Bu2SnO in toluene at high temperature (93–110 °C) for 24–72 h.

  Efficient transformations of inactive nitriles into 5-substituted 1H-tetrazoles in DMF in a microwave reactor are described. The present method is applied to the synthesis of tetrazolato-bridged dinuclear platinum(II) complex and tetrazole C-1-ribonucleoside phosphoramidite.
