[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
[结构:见正文]从二氯甲基膦或二氯甲烷膦酸酯作为含磷部分开始,使用了三种不同的方法合成二核苷甲烷膦酸酯[3'-NH-P(O)(CH3)O-5']。5'-DMT-3'-氨基-3'-脱氧胸苷和N(4)-苯甲酰基-5'-DMT-3'-氨基-2',3'-二脱氧胞苷用作氨基核苷前体,各自的3'保护的核苷(胸苷或N(4)-苯甲酰基-2'-脱氧胞苷)作为5'-羟基试剂。
