The reactions of t-BuLi, sec-BuLi and n-BuLi with CO in the presence of isothiocyanates and isocyanates gives, after hydrolytic work-up, α-oxothioamides, RC(O)C(S)NHR′, and α-oxoamides, RC(O)C(O)NHR′, respectively, in good yield. Competition from the direct reaction of RLi with the substrate is encountered only in the case of reactions of the n-BuLi/CO system with isocyanates.

The present invention relates to compounds that inhibit serine protease activity, particularly the activity of hepatitis C virus NS3-NS4A protease. As such, they act by interfering with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The invention further relates to compositions comprising these compounds either for ex vivo use or for administration to a patient suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a patient by administering a composition comprising a compound of this invention. The invention further relates to processes for preparing these compounds.
