Abstract: | structure: see text] Three different approaches were used for the synthesis of dinucleoside methanephosphonamidates 3'-NH-P(O)(CH3)O-5'], starting from dichloromethylphosphine or dichloromethanephosphonate as the phosphorus-containing moiety. 5'-DMT-3'-amino-3'-deoxythymidine and N(4)-benzoyl-5'-DMT-3'-amino-2',3'-dideoxycytidine were used as the aminonucleoside precursors and the respective 3'-protected nucleosides (thymidine or N(4)-benzoyl-2'-deoxycytidine) as the 5'-hydroxyl reagents. |
