  Synthesis, chemical and enzymatic reactivity, and toxicity of dithymidylyl-3′,5′-phosphorofluoridate and -phosphorothiofluoridate

  摘要：

  Dithymidylyl-3',5'-phosphorofluoridate and phosphorothiofluoridate were obtained by fluorinolysis of the P-Se bond in appropriate bisdimethoxytrityl selenomethyl esters. These compounds, which are hydrolytically unstable, are not inhibitors of snake venom, spleen phosphodiesterases and alkaline phosphatase. Neither compound is highly toxic.
