R. Alvarez et al., CONFORMATIONAL STUDIES OF 3'-SPIRONUCLEOSIDES (TSAO-T AND ANALOGS) BYNMR-SPECTROSCOPY, Nucleosides & nucleotides, 16(7-9), 1997, pp. 1399-1402
The conformational properties in solution of the prototype compound TS
AO-T (1) and its two analogues 2 and 3 have been determined by H-1 and
C-13 NMR techniques. The three compounds showed a sugar ring conforma
tion rare among HIV-inhibitory nucleosides, probably due to the presen
ce, at the 3'-position of the spiro moiety.
