The synthesis and antiviral activities of novel L-isomers 9–13 and modified D-guanine analogs 1d,e of recently reported anhydrohexitol nucleosides 1 are described. An efficient approach to known anhydrohexitol nucleoside precursor 2 from diacetone-D-glucose 3 is also reported.
The synthesis and antiviral evaluation of a series of (+-)-3,5- dihydroxypentyl nucleoside analogues related to acyclicnucleoside antiviral agents are reported. All purine and pyrimidinenucleoside analogues described in this paper have been obtained from 1-amino-5-(benzyloxy)pentan-3-ol. A synthesis of this amine is reported from 1-(benzyloxy)but-3-ene after epoxidation and regiospecific diethylaluminum

Nucleobase-functionalized β-peptides are a suitable scaffold for the construction of well-defined tertiary structures organized by nucleobase pair recognition. Since guanine-rich oligomers are especially known to form higher aggregates, an enantiomerically pure 7-deazaguanine (zG)-functionalized nucleo-β3-amino acid was synthesized from a β-lactam derivative as a key intermediate.
