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 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
We synthesized bicyclic ether sialidase inhibitors Such as tetrahydro-furan-2-yl. tetrahydro-pyran-2-yL and oxepan-2-yl derivatives related to zanamivir. These compounds substituted by diol at the C-3' and C-4' positions resulted in the retention of low nanomolar inhibitory activities against not only influenza A virus sialidase but also influenza A virus in cell culture. Compound I la in particular showed comparable efficacy in vivo relative to that of oseltamivir phosphate. (C) 2003 Elsevier Science Ltd. All rights reserved.
