An efficient procedure for SnCl2/KI-mediated allylation reactions of formaldehyde with a variety of allylic bromides in aqueous solution is reported. Under conditions developed in this effort, various homoallylic alcohols and 2-halohomoallylic alcohols are produced in good to excellent yields.
by the intermediacy of N-acyliminium species. A similar process applied to lactams 21b–25b affords the pyrrolizidine type compounds 26–35 through consecutive azonium-Cope rearrangement and N-acyliminium ringclosure. Additional results are concerned with the use of aromatic rings as π-nucleophiles.

The present invention discloses compounds of formula I and II 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.
