ABSTRACT
A synthesis of synthons which allow one to introduce 2'-deoxy-2'-fluoropyrimidine derivatives into the oligodeoxynucleotide chain by means of the standard solid phase phosphoramidite method has been developed. Oligonucleotides with 1-beta-D-arabinofuranosylcytosine were synthesized using either aC derivative with the unprotected 2'-OH group or O2,2'-anhydro-4-thiouridine. The synthesis of seven modified oligonucleotides (7 to 11 nucleotide residues) is described and their ability to form duplexes with complementary DNA have investigated as well as RNase H hydrolysis of hybrids formed by the E. coli 5S RNA and the obtained oligonucleotide probes.
