(±)-Gusanlung A, 8-oxyberberrubine and (±)-gusanlung D have been synthesized by radical cyclisation of the corresponding 2-aroyl-1-methylenetetrahydroisoquinolines. The 1H and 13C spectra of (-)-gusanlung D were found to be different

A series of palladium (and in some cases rhodium) catalysed regiospecific 5-exo-, 6-endo- and 6-exo-trig cyclisations of aryl iodides and vinyl bromides onto proximate alkenes or heteroaromatic rings (indole, pyrrole) lead to a wide variety of fused ring
