An efficient cascade bicyclization strategy for the construction of γ-lactam containing 3,3-disubstituted oxindole derivatives under silver catalysis is described. The method enables the sequential assembly of both unactivated and activated...
A AgSCF3-mediated tandem trifluoromethylthiolaton and cyclization of N-aryl-3-butenamides was developed. It showed divergent reactivities and enabled the selective syntheses of CF3S-substituted 3,4-dihydroquinolin-2-ones and azaspiro[4,5]dienones. The selectivity was achieved through different...
The synthesis of γ-lactam and related 2-oxazolidinone substituted quinone derivatives through a Ag2O-catalyzed cascade cyclization and functionalization of N-ary-4-pentenamides and N-aryl allyl carbamates has been developed.
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.
