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.

The reductive homocoupling of carbonylcompounds and heterocoupling of a carbonylcompound with an alkoxysilane were both effected smoothly with triethylsilane in the presence of a catalytic amount of bismuth bromide (1–3 mol%) under mild conditions. This ether-forming reaction was successfully applied to the single-step preparation of novel crownophanes with olefinic or acetylenic linkages.

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.
