A preparation of (1'R,2'S,3'R,4'S)-1-(2',3',4'-trihydroxycyclopent-1'-yl)-1
H-cytosine (5'-norcarbodine, 3) has formally been achieved in 2 steps from
(+)-(1R,4S)-4-hydroxy-2-cyclopenten-1-yl acetate (4) and cytosine. The L-li
ke enantiomer of 3 (that is, 6) is also reported using the enantiomer of 4
(that is, 7). In evaluating 3 and 6 for antiviral potential against a numbe
r of viruses, compound 3 was found to have activity towards Epstein-Barr vi
rus (EBV).
