abstract: A general synthetic method for 4'-hydroxymethyl-2',3'-anhydronucleosides from 1,2-O-isopropylidene-4-hydroxymethyl-alpha-D-xylofuranose is described. The condensation of 1,2-di-O-acetyl-3-O-methanesulphonyl-4-benzoyloxymethyl-5-O- benzoyl-D-xylofuranose with trimethylsilyl derivatives of N6-benzoyladenine and N2-palmitoylguanine in the presence of stannic chloride resulted in the corresponding nucleosides. After their treatment with NH4OH-EtOH, corresponding 2',3'-riboanhydronucleosides were isolated. Condensation of 1,2-di-O-acetyl-3-O-benzoyl-4-benzoyloxymethyl-5-O-benzoyl-D-xy lofuranose with trimethylsilyl derivatives of purines followed by selective deacetylation led to the nucleosides with free 2'-OH group. Their 2'-O-mesylation and epoxidering closure resulted in the isolation of 2',3'-anhydrolyxonucleosides with 38-44% yields. All the compounds synthesized did not inhibit HIV-1 reproduction in human H9 and PBL cell cultures nor HSV-2 and HCMV reproduction in vero cells up to 100 microM concentrations.
