Hepatitis C virus NS3-4A serine protease inhibitors: SAR of new P1 derivatives of SCH 503034
摘要:
Substitutions on the P-1 cyclobutyl side chain of SCH 503034 were studied by introduction of hydroxyl and fluoro substituents. Additionally, effects of. uoro substitution on other P1 moieties were evaluated. (C) 2008 Elsevier Ltd. All rights reserved.

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.

The first catalytic method for diastereo- and enantioselective synthesis of allylic boronates bearing a Z-trisubstituted alkenyl fluoride is disclosed. Boryl substitution is performed with either a Z- or E-allyldifluoride and is catalyzed by bisphosphine/Cu complexes, affording products in up to 99 % yield with >98:2 Z/E selectivity and 99:1 enantiomeric ratio. A variety of subsequent modifications
