Enantiospecific syntheses of (-)-anhydronupharamine, (-)-nupharamine, (-)-nuphenine, and (+)-3-epinupharamine are achieved starting from (-)- or (+)-carvone as chiral sources, in which a regioselective reductive fragmentation of the cyclopentane derivatives and an intramolecular aza-Wittig reaction were involved as key reactions.
