説明
Abstract The deoxyribonucleoside-3′-yl O-bis(1,1,1,3,3,3-hexafluoro-2-propyl) phosphite units (3) could be converted into the O-nucleosidyl phosphonate, O-2-cyanoethyl O-nucleosidyl phosphonate, and O-1,1,1,3,3,3-hexafluoro-2-propyl O-nucleosidyl phosphonothioate. Compound 3a was activated by methylimidazole to give the dithymidylate derivatives (8). The appropriately protected nucleosidyl phosphonates (3) were applied to the synthesis of oligodeoxyribonucleotides used as antisense oligonucleotides.
