Tropane
Tropane is a nitrogenous bicyclic organic compound. It is mainly known for a group of alkaloids derived from it, which include, among others, atropine and cocaine. Tropane alkaloids occur in plants of the families Erythroxylaceae and Solanaceae.
The nitrogen bridge is between C-1 and C-5; these two are asymmetric carbons, but tropane is optically inactive due to mirror symmetry.
8-Azabicyclooctane is known as nortropane or nor-tropane.
