摘要:
We report an efficient, one-flask route for synthesis of AZTp(S)p(CX2)pp(s)A and AZTp(S)p(CX2)pp(s)AZT, where X = H and X = F. This route makes use of the differential susceptibility to oxidation of H-phosohonate mono- and diesters, to allow a series of sequential reactions without requiring isolation of intermediates. These compounds are hydrolysis-resistant versions of the AZTppppA that results from excision of AZT by AZT-resistant HIV reverse transcriptase (RT). This family of compounds may therefore be useful in further study of the AZT excision reaction, as well as in drug design.
