Several "sugar" modified acyclic nucleoside analogues related to 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine (DHPG, 2) were synthesized and evaluated for antiviralactivity. The preparation generally involved the condensation of the acetoxymethyl ether of alcohols 6c-g and 10-12a with diacetylguanine to give adducts 7c-g and 14-16, which were then deprotected to afford analogues 9c-g and 17-19. Alternatively
anti-periplanar addition of hydrogenfluoride to oxiranes. Terminal epoxides give preferentially 2-fluoro-1-alcanols (e.g., 4) if an hydrogenfluoride/pyridine mixture is used in toluene medium while mainly 1-fluoro-2-alkanols (e.g., 5) result from the reaction with “Hünig's hydrofluoride” (i.e., the adduct of hydrogenfluoride an N-ethyldiisopropyl- amine). With 2-hydroxymethyl substituted oxiranes, predominantly

Several new acyclonucleosides have been synthesized from racemic epichlorhydrin or epifluorhydrin. This involves epoxide opening followed by chain elongation with iodomethyl phenyl sulfide and subsequent coupling of the phenylthioacetal with thymine. Deprotection afforded the title compounds 6, 8 and 18, whereas introduction of a phenylthio group at C-6 led to the three HEPT analogs, 13, 19, and 24.

converted into the corresponding fluorohydrins FCH2CH(OH)CH2OX by reaction with catalytic amounts of Bu4N+H2F3- and a molar excess of KHF2. Most of the protective groups (X) examined are stable under the above conditions, moreover stereogenic carbons are not affected.
