The present invention relates to novel pro-drugs of L-2'-deoxythreose nucleoside phosphonates, such as phosphoramidate, phosphorodiamidate and phospho-diester prodrugs. The invention also relates to a process for preparing these novel prodrugs of nucleoside phosphonates. The invention also relates to the use of these novel phosphonatemodified nucleosides to treat or prevent viral infections and their use to manufacture a medicine to treat or prevent viral infections, particularly infections with viruses belonging to the HBV family.
A synthetic scheme has been developed for the synthesis of 2′-deoxythreose phosphonate nucleosides from β-hydroxy-γ-butyrolactone and of 2′-azido erythrose phosphonate nucleosides from dihydroxydihydrofuran-1-one. In addition several α-l-arabinofuranose phosphonate nucleosides were synthesized starting from protected α-d-galactofuranose. Unfortunately, none of the synthesized compounds show activity
