| Abstract: | The synthesis of a self-complementary octanucleotide, d(G-G-T-T-A-A-C-C-), using a modified triester approach is described. The protected dinucleotides, d(Me2O)TribG(C1C6H4) ibG, d(Me2O)TrT(ClC6H4)T, d(Me2O)TrbzA(ClC6H4)bzA, and d(Me2O)TranC(ClC6H4)anC were synthesized by a one step triester procedure. After removal of the trityl group, the dinucleotides, dT(ClC6H4)T and danC (ClC6H4)anC were coupled to d(Me2O)TribG(ClC6H4)ibG and d(Me2O)TrbzA(ClC6H4)bzA, respectively to yield the respective tetranucleotides. The tetranucleotide, d(Me2O)TrbzA(ClC6H4)bzA(ClC6H4) and (ClC6H4)anC was detritylated and then coupled with d(Me2O)TribG(ClC6H4)ibG(ClC6H4)T(Cl6H4)T to give octanucleotide. The fully protected octanucleotide was deblocked by treatment with aqueous NH3 followed by acid and was characterized by nucleotide sequence analysis. |
