The present invention discloses compounds of Formula I or pharmaceutically acceptable salts, esters, or prodrugs thereof:
which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.

Reaction of anhydrous silverperchlorate, sym-collidine, and iodine (2:1:1 molar ratio) with cyclic alkenes and an excess of an alcohol in CH 2 Cl 2 affords trans-1,2-dialkoxycycloalkanes in high yields and purity. The reaction occurs via initial formation of the trans-iodoethers, which undergo Ag-assisted iodide abstraction to give the trans-diethers.
无水高氯酸银、sym-可力丁和碘(2:1:1 摩尔比)与环状烯烃和过量醇在 CH 2 Cl 2 中的反应以高产率和纯度提供反式-1,2-二烷氧基环烷烃。该反应通过反式碘醚的初始形成发生,该反式碘醚经过 Ag 辅助的碘化物提取得到反式二醚。
