The present invention features compounds of formula (I): and salts thereof, pharmaceutical compositions comprising said compounds, and uses of such compounds in treating or preventing viral infections, such as HCV infections, and diseases associated with such infections.
The exo-selective C-H cycloaddition of imidazoles to 1,1-disubstitutedalkenes has been achieved for the first time by using half-sandwich scandium catalysts. A wide range of imidazole compounds bearing various 1,1-disubstituted aliphatic alkenes, styrenes, dienes and enynes have been selectively converted in high yields to the corresponding bicyclic imidazole derivatives bearing -all-carbon-substituted
