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 present invention discloses compounds of formula I, or pharmaceutically acceptable salts, esters, or prodrugs thereof:
which exhibit antibacterial properties. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject in need of antibiotic treatment. The invention also relates to methods of treating a bacterial infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention. The invention further includes process by which to make the compounds of the present invention.
Structurally Divergent Synthesis of Azetidines, 5,6‐Dihydro‐1,3‐oxazines and 2,3‐Dihydro‐1,4‐oxazines through Palladium‐Catalyzed Tandem Allylic Substitution Reaction
A regiodivergent synthesis of azetidines, 5,6-dihydro-1,3-oxazines and 2,3-dihydro-1,4-oxazines has been achieved through palladium-catalyzed tandem allylicsubstitution reaction. This protocol provides a variety of heterocycles in satisfactory yields with good to excellent regioselectivities under mild reaction conditions.
