Synthesis of Deoxydinucleoside Phosphates Containing 4-Thio Substituted Pyrimidine Nucleobases

The preparations, by the hydrogenphosphonate approach in solution, of the five pyrimidine deoxydinucleoside monophosphates 14a, 14b, 16a, 16b and 17 containing a 4-thiosubstituted pyrimidine nucleobase at either their 3'- or 5'-end are described.These syntheses were conveniently accomplished using 4-thionucleoside derivatives having their sulfur function protected by S-pivaloyloxymethylation.The behaviour of unprotected 4-thionucleoside derivatives was also investigated and they were shown to give comparable overall yields.
