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.

and biochemical stability. We have developed bicyclic tetrapeptide HDAC inhibitors based on different cyclic tetrapeptide scaffolds. For the synthesis of these bicyclic tetrapeptides, two cyclization steps, namely, peptide cyclization and fusion of aliphatic side chains by ring closing metathesis (RCM) were involved. In the course of these syntheses, we have established two facts: a lower limit of aliphatic

The present invention provides a process for the preparation of a nonracemic a-amino acid derivative from an optically active N-acyl lactam using an organometallic reagent to effect the opening of the ring followed by reduction of the ketone carbonyl to an alcohol or a methylene, or by a reductive amination to an amine, or by a ketalization reaction.
