Article abstract of DOI:10.1248/cpb.39.2216

Total synthesis of naucleficine (3a) was accomplished for the first time via an alkaloid, oxogambirtannine (3b), which was efficiently prepared by photocyclization of the o-methoxy-enamide 2b. The method is a practical one, suitable for large-scale preparation.
