Substituted tropanes are a group of psychoactive compounds that include a tropane ring in their structure. Prominent examples include certain stimulants like cocaine and its derivatives as well as deliriants like atropine and scopolamine.
Tropane alkaloids are molecules which contain a substituted tropane ring in their structure. Tropane is a nitrogen-containing bicyclic organic molecule which consists of a piperidine and pyrrolidine ring fused at carbons R1 and R5 along with an additional methyl substitution at RN. Tropane alkaloids are commonly substituted at R3 with an ether bridge (as seen in scopolamine, atropine, hyoscyamine, and cocaine).
Tropane alkaloids are seen throughout organic chemistry and include psychoactive and anaesthetic compounds.
