A number of variously substituted phenanthridines have been synthesized using the newly developed methodology under mild conditions. The Hendrickson reagent initiated cascade annulation, which is composed of a mild conversion of stable amide precursor to highly reactive imido-carbonium intermediate and a subsequent intramolecular Friedel-Crafts reaction, successfully served as the key method.

dehydrogenative kinetic resolution of cyclic secondaryamines using air as an oxidant has been reported. The economical and practical method is applicable to a series of cyclic benzylic amines, including 5,6-dihydrophenanthridines and 1,2-dihydroquinolines, with diverse functional groups at the α position in high yields with excellent enantioselectivities. The direct dehydrogenative kinetic resolution of

The iron(III)-catalyzed cross-coupling reaction between functionalized arylcopper reagents and aromatic iodides bearing an amidefunction or an unprotected quinolinone leads smoothly to polyfunctionalized biphenyls in excellent yields due to an intramolecular chelating effect of the amide group.
