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.
