The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof:
which inhibit RNA-containing virus, particularly the hepatitis C virus (HCV). Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention. The present invention relates to novel antiviral compounds represented herein above, pharmaceutical compositions comprising such compounds, and methods for the treatment or prophylaxis of viral (particularly HCV) infection in a subject in need of such therapy with said compounds.

The highly enantioselective cinchona alkaloid-catalyzed Mannich reaction of dicarbonyl compounds with α-amidosulfones as acyl imine precursors is described. The reaction requires 10 mol % of the cinchona alkaloid catalyst, which serves as a general base to generate acyl imines in situ, and aqueous Na2CO3 to maintain the concentration of free alkaloid catalyst. The reaction products are obtained in

Enzymatic Synthesis of Enantiomerically Pure β-Amino Ketones, β-Amino Esters, and β-Amino Alcohols with Baeyer-Villiger Monooxygenases

The enzymatic kinetic resolution of a broad set of β‐amino ketones was investigated by using a collection of 16 Baeyer–Villigermonooxygenases from different bacterial origins, which display various substrate specificities. Within this platform of enzymes excellent enantioselectivities (E>200) were found towards aliphatic and aromatic 4‐amino‐2‐ketones, and some enzymes even showed opposite enantioselectivity
