syntheses of L-carbocyclic 2',3'-didehydro-2',3'-dideoxy- and 2',3'-dideoxypyrimidine and purine nucleoside analogues were accomplished, and their anti-HIV and anti-HBV activities were evaluated. The key intermediate, (1S, 4R)-1-benzoyloxy-4-(tert-butoxymethyl)cyclopent-2-ene (7), was prepared by benzoylation of the alcohol 2, selective deprotection of the isopropylidene group of 3, followed by thermal elimination
Antiviral and antitumor compounds are disclosed of general formula: ##STR1## wherein Z is H, OH or NH.sub.2, Y is CH or N, the bond indicated by C.sub.1 '--C.sub.2 ' is absent or, in combination with the C.sub.1 '--C.sub.2 ' bond is the unit CH.dbd.CH, and X is selected from the group consisting of H, N(R.sub.2), SR, OR or halogen, wherein R is H, lower (C.sub.1 -C.sub.4)alkyl, aryl or mixtures thereof, and the pharmaceutically acceptable salts thereof.
