Synthesis and structual assignment of novel 5´-epimeric 3´deoxy-3´,4´-didehydronucleoside-5´-C-phosphonates
Petrová, Magdalena ; Buděšínský, Miloš ; Klepetářová, Blanka ; Rosenberg, Ivan
Epimeric 5´-(RS) dialkyl 3-deoxy-3´,4´-didehydro-5´-C-phophonates were prepared by nucleophilic addition of various dialkyl phosphites to 3´-deoxy-3´,4´-didehydronucleoside-5´-aldehydes. Successful separation,crytstallisation and X-ray analysis of a pair of epimeric 5´-C-phosphonates, followed by correlation with a series of NMR parameters, led to efficacious configuration assignment of individual epimers in the mixtures.
