Vi. Kobylinskaya et al., SYNTHESIS OF FLUORO AND AZIDO DERIVATIVES OF PURINE NUCLEOSIDES FROM NUCLEOSIDES 2',3'-CYCLOSULPHATES, Bioorganiceskaa himia, 20(11), 1994, pp. 1226-1230
2',3'-Cyclosulphate derivatives of inosine and adenosine were synthesi
zed by the action of sulphuryl chloride on N,O-benzoyl nucleosides in
the presence of triethylamine. Reactions of nucleophilic substitution
of the sulphate group led to fluoro and azido derivatives of the nucle
osides, which, according to the H-1- and F-19-NMR spectra, are 3'-subs
tituted 3'-deoxyxylofuranosides.
