摘要:Disclosed are dihydrobenzoxazinone compounds, dihydroquinolone compounds, and methods of their synthesis. The disclosed compounds may be prepared by reacting a benzoxazinedione compound and a ketone compound in the presence of an N-heterocyclic carbine (NHC) catalyst to perform a NHC-catalyzed decarboxylative cycloaddition. The disclosed compounds may be utilized to treat diseases and disorders associated with the biological activity of dihydrobenzoxazinone compounds and dihydroquinolone compounds.
