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.

Three-membered cyclic sulfones (episulfones) undergo substitution on treatment with base-electrophile mixtures, such as LDA-Me(3)SiCl and tBu-P4-phosphazene base-PhCHO, to give either substituted episulfones or the corresponding alkenes following loss of SO2.

Novel Episulfone Substitution and Ring-Opening Reactions via α-Sulfonyl Carbanion Intermediates
作者:Nigel S. Simpkins
DOI:10.1080/10426509708545519
日期:1997.1.1
Three-membered cyclic sulfones undergo substitution on treatment with baseelectrophile mixtures, such as LDA-Me3SiCl and tBu-P4-phosphazene base-PhCHO, to give either substituted episulfones or the corresponding alkenes following loss of SO2. In the absence of Me3SiCl, reaction of episulfones with LDA results in ring-opening to give alkenyl sulfinate intermediates, which can be alkylated to give (E)-alkenyl
