5´-Epimeric 3´-deoxy-3´,4´-didehydronucleoside-5´-C-phosphonates: synthesis and structural assignment by NMR and X-ray analyses

Epimeric 5'-(RS) dialkyl 3-deoxy-3',4'-didehydro-5'-C-phosphonates were prepared by nucleophilic addition of various dialkyl phosphites to 3'-deoxy-3',4'-didehydronucleoside-5'-aldehydes. Whereas direct NMR configuration assignment for the C...

Nucleoside 5'-C-phosphonates: reactivity of the alpha-hydroxyphosphonate moiety

We found that various dialkyl phosphites, dialkyl trimethylsilyl phosphites, and tris-trimethylsilyl phosphite reacted smoothly with nucleoside 5'-aldehydes to afford epimeric nucleoside 5'-C-phosphonates in high yields....
