Synthesis of 5'-Triphosphate Mimics (P3Ms) of 3'-Azido-3',5'-Dideoxythymidine and 3',5'-Dideoxy-5'-Difluoromethylenethymidine as HIV-1 Reverse Transcriptase Inhibitors
摘要:
3'-Azido-3,5-dideoxythymidine 5-phosphonate and 3',5-dideoxy-5-difluoromethylenethymidine 5'-phosphonate were prepared by multistep syntheses. The nucleoside 5-phosphonates were converted to their triphosphates and triphosphate mimics (P3Ms) containing beta,gamma-difluoromethylene, beta,gamma-dichloromethylene, or beta,gamma-imodo by condensation with pyrophosphate or Pyrophosphate mimics, respectively. Inhibition of HIV-1 reverse transcriptase by the nucleoside P3Ms is briefly discussed.
