Ag2O mediated N-demethylation and oxidative opening of indenopyrido[2,1-a]isoindolones. Efficient access to polysubstituted 1-azafluorenones†
Abstract
Highly functionalized 1-azafluorenones were obtained from indeno[2,1-a]isoindolones through Ag2O-mediated cascade reaction. The cascade process includes the oxidation of vicinal
