The total syntheses of tabernanthine and ibogaline were enabled by application of a thermal coupling of nosyl aziridine and indoles in eight steps each, 10 and 14 % yield respectively. A Friedel-Crafts type macrocyclization facilitated key C−C bond formation. Regio- and diastereoselective hydroboration-oxidation of the resultant macrocyclic alkene enabled C−N bond formation and furnished the completed
