A novel methodology for the synthesis of 3-alkenyl indolines through the reaction of in situ generated allenes with N-benzylic Csp3-H has been developed. The reaction was realized by Pd(0) catalyzed...
By starting from a common substrate, 2-aminobenzaldehyde, both acridines and acridones were prepared. The former were generated in high yields by copper-catalyzed N-arylation followed by acid-mediated cyclization while the latter were obtained by double copper-catalyzed N-arylation followed by cyclization under the same reaction conditions. Moreover, acridine was subjected to deprotometalation by recourse

A copper-catalyzed approach for the synthesis of acridones via C–Cbondcleavage and intramolecular cyclization using air as the oxidant under neutral conditions is described. This transformation offers an alternative method to prepare medicinally important acridones and a new strategy for C–Cbondcleavage.
