Total Syntheses of (±)-Gusanlung A, (±)-Gusanlung D and 8-Oxyberberrubine and the Uncertainty Concerning the Structures of (-)-Gusanlung A, (-)-Gusanlung D and 8-Oxyberberrubine

Total Syntheses of (±)-Gusanlung A, (±)-Gusanlung D and 8-Oxyberberrubine and the Uncertainty Concerning the Structures of (-)-Gusanlung A, (-)-Gusanlung D and 8-Oxyberberrubine

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