The concise synthesis of Amaryllidaceae alkaloids, such as anhydrolycorinone, anhydrolycorin-7-one, assoanine, and oxoassoanine, which have a pyrrolophenanthridine skeleton, was achieved in moderate yield using the Pd-mediated biaryl coupling reaction of

The biaryl coupling reaction of 1-benzoyl-7-iododihydroindole derivatives using Pd reagent was examined. 1-[(1,3-Benzodioxol-5-yl)carbonyl]-7-iodo-2,3-dihydroindole gave 4,5-dihydro-7H-[1,3]dioxolo[4,5-k]pyrrolo[3,2,1-de] phenanthridin-7-one, which was formed by connection to a more hindered carbon, as a major product. 1-(3,4-Dimethoxybenzoyl)-7-iodo-2,3-dihydroindole gave oxoassoanine and 10,11-dimethoxy-4,5-dihydropyrrolo[3,2,1-de]-phenanthridin-7-one in an almost equal ratio.

The concise synthesis of the pyrrolophenanthridine alkaloids 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.
