Stereochemical Investigations of Samarium(II) Iodide-Promoted 5-Exo and 6-Exo Ketyl-Olefin Radical Cyclization Reactions
摘要:
Samarium(II) iodide (SmI2)-promoted ketyl cyclizations of several substituted, unsaturated ketones, providing various cyclopentyl and cyclohexyl systems, have been investigated. The resulting experiments provide stereochemical insight into these reactions and in addition outline the synthetic potential of these 5-exe and 6-exo radical cyclization processes.
The present invention relates to macrocyclic compounds of formula (I) that are useful as inhibitors of the hepatitis C virus (HCV) NS3 protease, their synthesis, and their use for treating or preventing HCV infections.
