The invention relates to methods of treating COVID-19 in a patient by administering therapeutically effective amounts of certain SARS-CoV-2 inhibitor compounds or pharmaceutical compositions containing them to a patient in need thereof. The invention also relates to inhibiting SARS-CoV-2 coronavirus viral replication activity comprising contacting SARS-CoV-2-related coronavirus protease with a therapeutically effective amount of a SARS-Cov-2 protease inhibitor, such as a SARS-Cov-2 3CL protease inhibitor and compositions comprising the same

Development of a reductive coupling of a β-keto-lactone and an aldehyde is described, in which the Hantzsch ester serves as an inexpensive and convenient reducing agent. Structural features in the β-keto-lactone rendered standard reductive coupling conditions ineffective, requiring development of a specific addition and temperature protocol. Identification of one of the reactants as Ames positive required
This paper describes the optimization efforts to establish an enabling synthesis to provide multigram quantity of PF-00868554, an HCV polymerase inhibitor currently in phase II clinical evaluations.
