oxazolylimidazoles, -thiazoles, and -oxazoles is gained from a masked α-haloketone attached to the 2-position of the oxazole ring. 3-Bromo-2,2-diethoxy-N-(2-oxoalkyl)propionamides readily cyclize to generate the key 5-substituted 2-(2-bromo-1,1-diethoxyethyl)oxazole intermediate. 3-bromo-2,2-diethoxypropionic acid - α-haloketones - cyclizations - heterocycles - oxazoles
This disclosure concerns novel compounds of Formula (I) or 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.
