The first enantioselective total syntheses of indole alkaloids of the condylocarpine type are reported. (+)-Condylocarpine, (+)-isocondylocarpine, and (+)-tubotaiwine were prepared in high enantiomeric purity (er > 99:1) from (1S,5R)-hexahydro-1,5-methano-1H-azocino[4,3-b]indole-12-one 7b by way of five or six isolated intermediates.
