Abstract:A library of 18 polysubstituted 4-quinolones was conveniently prepared via simple and practical protocol involving N-alkylation of 2-(3-oxoindolin-2-yl)acetonitriles and following NaH-induced ring expansion. The current two-step approach provides feasible access to a subclass of N-protected C3-aryl-substituted 2-phenyl-4-quinolones starting with or just one step away from commercially available 2-arylindoles and nitrostyrenes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
