  摘要：

  硫代磷酰胺酯类似物[(RP)-和(SP)-3′,5′-Tnp(s)T]2以及磷酰胺酯类似物[3′,5′-TnpT]3的胸苷基-3′,5′-胸苷被制备出来，并在363.2 K下通过反相高效液相色谱法跟踪了它们在pH范围1至8的水解反应。在pH < 6时，酸催化的P-N3′键断裂（[H+]的一级反应）在3′,5′-Tnp(s)T和3′,5′-TnpT中都会发生，前者比后者稳定约12倍。在pH > 4时，Tnp(s)T会经历两种竞争性的pH无关反应，去硫化（生成TnpT）和去嘧啶化（N-糖苷键断裂），这两种反应的速率是同一数量级的。同样，3′,5′-TnpT在pH > 5时，pH无关的去嘧啶化与P-N3′键断裂竞争。

  摘要：

  3'-Amino-3'-deoxy-5'-O-(4,4'-dimethoxytrityl)-3'-N,5(R)-C-ethylenethymidine (6)was synthesized starting from 3'-azido-3'-deoxythymidine. Condensation of 6 with 5'-O-(H-phosphonyl)thymidine and 5'-O-(p-nitrophenoxycarbonyl)thymidine derivatives gave dinucleotide and dinucleoside derivatives, respectively, which were incorporated into oligodeoxynucleotides (ODNs). Tm data of the modified ODNs are also presented.

  The diastereomeric thiophosphoramidate analogs [(RP)- and (SP)-3′,5′-Tnp(s)T] 2 and the phosphoramidate analog [3′,5′-TnpT] 3 of thymidylyl-3′,5′-thymidine were prepared and their hydrolytic reactions over the pH-range 1–8 at 363.2 K were followed by RP HPLC. At pH < 6, an acid-catalyzed P–N3′ bond cleavage (first-order in [H+]) takes place with both 3′,5′-Tnp(s)T and 3′,5′-TnpT, the former being about 12 fold more stable than the latter. At pH > 4, Tnp(s)T undergoes two competing pH-independent reactions, desulfurization (yielding TnpT) and depyrimidination (cleavage of the N-glycosidic bond) the rates of which are of the same order of magnitude. Also with 3′,5′-TnpT the pH-independent depyrimidination competes with P–N3′ cleavage at pH > 5.
