We herein report a general, practical, and highly efficient method for asymmetricsynthesis of a wide range of chiral vicinal diamines via reductive coupling of imines templated by chiral diboron. The protocol features high enantioselectivity and stereospecificity, mild reaction conditions, simple operating procedures, use of readily available starting materials, and a broad substrate scope. The method

[EN] 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. [FR] La présente invention concerne des composés répondant à la formule I ou des sels, des esters, ou des promédicaments pharmaceutiquement acceptables de ces composés, qui inhibent l'activité de la sérine protéase, en particulier l'activité de la protéase NS3-NS4A du virus de l'hépatite C (VHC). En conséquence, les composés de la présente invention interfèrent avec le cycle de vie du virus de l'hépatite C et ils se révèlent également utiles en tant qu'agents antiviraux. La présente invention concerne en outre des compositions pharmaceutiques contenant les composés susmentionnés, destinés à être administrés à un sujet souffrant d'une infection par le VHC. L'invention concerne également des procédés de traitement d'un sujet atteint d'une infection par le VHC par l'administration d'une composition pharmaceutique contenant les composés de la présente invention.
