validated targets for direct-acting antiviral therapies. The NS5B polymerase may be inhibited directly through the action of nucleosides or nucleotideanalogues or allosterically at a number of well-defined sites. Herein we describe the further development of a series of thiophene carboxylate allosteric inhibitors of NS5B polymerase that act at the thumb pocket 2 site. Lomibuvir (1) is an allosteric

(BH3THF)-T-. can reduce polypeptides to polyamines with retention of chirality. The resulting polyamines are intriguing general platforms for asymmetric catalysis, given the diverse structures available and their relative ease of synthesis. We have constructed a number of chiral pyridoxamine catalysts based on reduced peptides. These compounds transaminate alpha-ketoacids with moderate to good enantioselectivity, while their peptidyl counterparts show almost no chiral induction. (c) 2005 Elsevier Ltd. All rights reserved.

A compound is represented by Structural Formula (I):
or a pharmaceutically acceptable salt thereof, wherein the variables of Structural Formula (I) are as described in the specification and the claims. A pharmaceutical composition comprises a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier of excipient. A method of treating a HCV infection in a subject comprises administering to the subject a therapeutically effective amount of a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof. A method of inhibiting or reducing the activity of HCV polymerase in a subject or in a biological in vitro sample comprises administering to the subject or to the sample a therapeutically effective amount of a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof.
An unprecedented Ru-catalyzed directasymmetric reductive amination of α-keto amides with ammonium salts has been achieved. This protocol provides an efficient and practical way for the synthesis of diverse enantioenriched α-aryl- or alkyl-substituted N-unprotected unnatural α-amino acids and N-unprotected β-branched α-amino acids. Further follow-up transformations enable access to drug intermediates
