Preparative routes to the previously unknown (–)-cis-caran-trans-2-amine, (+)-cis-caran-cis-4-amine, (–)-cis-caran-trans-4-amine, (+)-cis-caran-cis-5-amine, and (–)-cis-caran-trans-5-amine are described, and their configurations are established. The (+)-caranamine prepared by Baeyer and by Menon and Simonsen is probably the enantiomorph of (–)-trans-caran-cis-2-amine now described. The probable conformations
