Synthesis And Anti-Hiv Activity Of Cyclic Pyrimidine Phosphonomethoxy Nucleosides And Their Prodrugs: A Comparison Of Phosphonates And Corresponding Nucleosides
摘要:
Cyclic phosphonomethoxy pyrimidine nucleosides that are bioisosteres of the monophosphate metabolites of HIV reverse transcriptase (RT) inhibitors AZT, d4T, and ddC have been synthesized. The RT inhibitory activities of the phosphonates were reduced for both dideoxy (dd) and dideoxydide-hydro (d4) analogs compared to the nucleosides. Bis-isopropyloxymethylcarbanyl (BisPOC) prodrugs were prepared on selected compounds and provided > 150-fold improvements in antiviral activity.

Two thymidyl-tetrahydrofuranylthymine dimers, 15 and 16, were synthesized stereospecifically in good yield via a Vorbruggen-type reaction between glycol ether 4 or propoxy alcohol 7 and acetate 12.
