dcterms:description
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 C5' atom bearing the phosphoryl and hydroxy groups using the J (P,H4') and J (H5',H4') coupling constants is impossible due to the absence of the H4' atom, successful separation, crystallisation 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.
