Abstract
The acyclic azanucleosides with 2-, 3-, or 4-aminobenzenesulfonyl function at the nitrogen atom of the sugar mimic were prepared by coupling of 2-, 3-, or 4-nitro-N-(2-pivaloyloxyethyl)-N-(pivaloyloxymethyl)benzenesulfonamide with the silylated pyrimidine nucleobases followed by the reduction of the nitro group with sodium dithionite in aqueous solution or the palladium-catalysed transfer hydrogenation. The azanucleosides were evaluated for, but found to be devoid of, activity against several RNA- and DNA-viruses in vitro.
