SYNTHESIS OF A MACROCYCLIC HCV PROTEASE INHIBITOR

摘要

The present invention provides a method of synthesis of a macrocyclic compound known as a potent inhibitor of a protease produced by the hepatitis C virus (HCV). Inhibition of the viral protease blocks assembly of mature viral particles in an infected mammalian host. The method of synthesis involves a ring-closing metathesis step using a ruthenium catalyst. Hydrogenation and boronate deprotection provide the HCV protease-inhibitory product.
