This disclosure concerns novel compounds of Formula (I) as defined in the specification and compositions comprising such novel compounds. These compounds are useful antiviral agents, especially in inhibiting the function of the NS5A protein encoded by Hepatitis C virus (HCV). Thus, the disclosure also concerns a method of treating HCV related diseases or conditions by use of these novel compounds or a composition comprising such novel compounds.

with ethyl acetate as the solvent. A simple iron- and silylchloridecatalyzed method for the preparation of symmetrical and nonsymmetrical ethers is presented. Various aldehydes and ketones were reductively etherified by using triethylsilane as a reducing agent in the presence of 2 mol% of iron(III) oxo acetate and 8 mol% of chloro(trimethyl)silane. The reactions can be carried out at ambient temperatures

A polycarbonate composition having improved resistance to γ-ray radiation, containing 0.01 to 10 parts by weight of a benzyl ether or benzylthioether derivative or the like. This polycarbonate resin composition is almost free from yellowing by γ-ray radiation in air or O2-free atmosphere, and is suitable for use in medical molded articles which are sterilized by γ-ray radiation.
