Practical asymmetric synthesis of a chronic hepatitis C virus nucleoside cyclic prodrug

C

hronic hepatitis C virus (HCV) is a liver disease that has infected an estimated 130 to 150 million people worldwide as

of 2016 and killed an estimated 500,000 people around the world annually. In spite of several medicine therapies for the

treatment of HCV being available, treatment failure and resistance still remain a clinical challenge. For these reasons, the search

for effective antiviral agents to combat HCV is an ongoing endeavor within the global medical/pharmaceutical community. As

part of an ongoing drug discovery program in our laboratories, the title compound has been identified as one such selective

and potent inhibitor of HCV NS5B nucleoside polymerase. This nucleoside cyclic prodrug is a complex, densely functionalized

small molecule, which represents numerous challenges for chemical synthesis. Herein, we report a new asymmetric, practical

synthetic route, which features several remarkably diastereoselective and high yielding transformations for the synthesis of the

target starting from readily available starting materials.
