Article abstract of DOI:10.1246/cl.1986.739

(+/-)-Chelamine and (+/-)-chelidonine, B/C cis hexahydrobenzophenanthridine alkaloids were stereoselectively synthesized from coptisine via the key intermediate, which was also converted to fully aromatized benzophenanthridine alkaloids, sanguinarine and dihydrosanguinarine.
