  Syntheses of 4′-spirocyclic phosphono-nucleosides as potential inhibitors of hepatitis C virus NS5B polymerase

  摘要：

  To discover novel nucleosides as potential antiviral agents, 4'-spirocyclic phosphono-nucleosides were designed to mimic the monophosphate of R-1479, a known nucleoside inhibitor of HCV NS5B. Bypassing the first kinase step to nucleoside monophosphate is viewed as advantageous since this phosphorylation is often observed as the rate-limiting transformation to the active NTP for many nucleosides. Efficient synthetic routes were developed with a triphenylphosphine-iodine cyclization reaction as the key step to form the tetrahydrofuran 4'-spirocycle. The desired 4'-spirocyclic phosphono-cytidine analogs 12a, 12b, and 16 were prepared in 11 steps. (C) 2014 Elsevier Ltd. All rights reserved.
