  The 1,1-Dianisyl-2,2,2-trichloroethyl Moiety as a New Protective Group for the Synthesis of Dinucleostde Trifluoromethylphosphonates

  摘要：

  The new 1,1-Dianisyl-2,2,2-trichloroethyl moiety (DATE) is used as an acid and base stable protective group for nucleosides. 5'-O-DATE-thymidine and 3'-O-acetylthymidine are phosphorylated with CF3P(NR(2))(2) to the corresponding thymidine trifluoromethylphosphonous amidites. These building blocks are coupled with appropriate protected thymidines to a dinucleotide trifluoromethylphosphonate.

  The phosphorylating reagents CF3P(NMe(2))Cl and CF3P(NEt(2))Cl are used to phosphorylate the 3'-hydroxyl moiety of several protected 2'-deoxynucleosides yielding the corresponding nucleoside trifluoromethyl phosphonamidites. Their scope and limitations towards amidite activation are investigated but, however, their behavior is completely different to commonly used nucleoside phosphorus amidites.
