Novel 1-(1-benzyl-1H-indol-3-yl)-N,N,N-trimethylmethanaminium iodides are competitive antagonists for the human α4β2 and α7 nicotinic acetylcholine receptors
The concisesynthesis of the pyrrolophenanthridinealkaloids such as anhydrolycorine, assoanine, anhydrolycorin-7-one, and oxoassoanine, was achieved using the Pd-catalyzed biaryl coupling reaction of 1-(2-halobenzyl)-2,3-dihydroindole by applying the regioselective C-H activation method with intramolecular coordination of the benzylamino group to Pd.
