A total synthesis of (−)-aspidophytine and the first total syntheses of its congeners, (+)-cimicidine and (+)-cimicine, were accomplished in a divergent manner. Construction of the aspidosperma skeleton was executed by Fischerindolesynthesis between substituted phenylhydrazines and tricyclic aminoketone. The regiochemistry of the Fischerindolesynthesis was strongly dependent on the choice of acid
