Rousseaux, Liegault, and Fagnou reported the elegant formation of quinoline and tetrahydroquinoline derivatives via a Pd(0)-catalyzed C-H activation of cyclopropane methylene bond [26]. Both bromophenyl and chlorophenyl cyclopropyl carbamates 31 and 32 were found to be suitable substrates for the transformation into dihydroquinoline 33, albeit under slightly different conditions (Scheme 5). It was found that the resulting dihydroquinolines 33 were prone to decomposition thus protocols for either oxidation or reduction of the unstable intermediates were developed. A variety of substituents (nitro, cyano, trifluoromethyl, methoxy, ester)...
