The preparation of a series of novel 6-(β-D-ribofuranosyl)-2-alkyl/aryl-6H-imidazo[1,2-c]pyrimidin-5-one nucleosides and the 2-nitrile nucleosides, 6-(β-D-ribofuranosyl)-5-oxo-5,6-dihydro-imidazo[1,2-c]pyrimidine-2-carbonitrile and 2R and 2S isomers of 6-(β-D-ribofuranosyl)-5-oxo-2,3,5,6-tetrahydro-imidazo[1,2-c]pyrimidine-2-carbonitrile, is described using two synthetic approaches. The nucleoside mimetics described were evaluated against a wide range of viral types and strains in cell culture. With the exception of one nucleoside, which displayed anti-CMV activity at toxic concentrations, none of the compounds showed antiviral activity most likely due to a lack of substrate recognition by viral and/or cellular nucleoside kinases.
